lesshastehttps://bugs.launchpad.net/ubuntu/+source/linux/+bug/224561 seems to indicate that my DVD drive is called hda but apparently there is hdX naming anymore in Hardy10:54
lesshasteogra from #ubuntu-bugs asked me to confirm that this is indeed the problem10:55
aboganiArghhhh! Why nvidia kernel driver required manual depmod -a to work (after today Hardy update)?????11:07
lesshasteabogani: :)11:08
aboganilesshaste: :-?11:09
tjaaltonabogani: there were no updates related to that..11:10
aboganiIt isn't first time...11:12
tjaaltonbut it's not the updates that causes it11:12
aboganiI suspect that lum break something module.dep related...11:17
tjaaltondo you use hardy-proposed?11:18
aboganiYeah11:18
tjaaltonthere are plenty of bugs against lrm about people needing to reinstall the driver every time etc11:18
tjaaltonbut too scary for me to debug ;)11:18
aboganitjaalton: Ahhhh ok! Are those bugs related only on lrm or on lum also?11:22
aboganitjaalton: Thanks! :-)11:22
tjaaltonabogani: no idea, people at least assume it's X which broke their setup11:45
aboganitjaalton: Thank you very much! :-)11:45
tjaaltonabogani: feel free to find the culprit ;)11:46
abogani:-)11:46
tseliot*cough* DKMS *cough* :-P11:47
* tseliot exits DKMS zealot mode11:48
tjaaltonI don't think DKMS would help here11:49
tjaaltonsince the modules are there11:49
tjaaltonthey just aren't getting loaded or something like that11:50
tseliottjaalton: I was kidding ;) . It's weird that they are not loaded. It never happened here11:55
tjaaltonfor me neither11:56
tseliottjaalton: BTW I think we should have a look at all the warnings which dpkg-shlibdeps shoots when the lrm are built12:16
tseliotwe can do it in Intrepid12:17
tjaaltontseliot: those should be harmless12:20
tjaaltonbut yes12:21
tseliottjaalton: yes, I know but I would like to see why it complains when I have the time12:21

qenseWhat's the purpose of the new 'envy' kernels?16:47
JanCenvy kernels?17:04
qensethere are kernle packages with envy in their name17:09
qenseand nvidia drivers with envy in their name, ati drivers too17:09
lagayou've probably installed envy-ng17:09
lagai can't see envy kernels here17:10
qenseI didn't installed envy-ng as far as I know17:11
qensebut I do have hardy-proposed enabled17:12
qenseah17:12
qensethere are ati or nvidia drivers with envy in thier name17:12
qenseis it going to be used by default in intrepid?17:13
tseliotqense: those are the drivers which I can update without touching the default lrm17:13
qenseand that's better?17:14
tseliotjust different17:15
lagai didn't know that NEW stuff was supposed to go through proposed. nice17:15
tseliotthey use DKMS17:15
qenseand DKMS can load modules dynamically whil the kernel is running?17:15
tseliotit auto-installs the modules if the kernel doesn't have one. It can do it at boot or when the package is installed17:16

fokaHi!  Has anyone run into a problem with Ubuntu 8.04 LiveCD with rtl8169_init_one causing a kernel Oops and then failing to boot?  :-)20:21
rtgfoka: as a matter of fact, we were just working on that. see http://people.ubuntu.com/~tspindler/r8169/20:25
fokartg, Very cool!  Thanks!  (And packaged by Torsten too!  Nice!  We've met in Beijing.  :-))20:26
rtgI'll likely include it as an SRU upload, but the Live CD won't get reissued until 8.04.1.20:26
fokartg, Is this the solution for the problem that caused the bug?   http://lkml.org/lkml/2008/4/17/29820:28
rtgfoka: I don't know. I haven't looked at Torsten's patch. The other r8169 bug I've been following crashes in PCI probe code, so it may be related.20:29
fokartg, Yes, I finally managed to get 8.04 installed by disabling the on-board LAN in the BIOS.  :-)20:29
fokartg, One more thing that I'd like to ask: Is it normal (while still in initrd) that dmesg shows logs with missing numbers?  20:30
fokartg, What I mean is this:  [    0.000] Linux version 2.6.2-1-generic (buildd@palmer) (gcc version 4.2.3 (Ubuntu 4.2.3-2ubuntu7)) #1 SMP Thu Apr 1 1:2:4 UTC 20 (Ubuntu 2.6.2-1.3-generic)20:30
rtgfoka: thats essentially what the guy in Taiwan ended up doing, though he used language that made me think he clipped leads to the part.20:30
rtgfoka: are you on an Atom based board? My taiwan guy had exactly the same issue.20:31
rtgfoka: I had a hell of a time deciphering his stack trace 'cause random characters were missing.20:32
fokartg, No, not an Atom AFAIK, but a desktop motherboard with 945 chipset.20:32
rtgfoka: straight video though? not serial console?20:33
fokartg, I could read the full text if I press "Shift-PageUp".20:33
rtgfoka: so its in the display RAM, but isn't getting rendered at speed.20:34
fokartg, But to save typing, I did a "dmesg > dmesg.txt" and then copied it to a USB stick (by manually modprobing sd_mod and usb-storage first)20:34
fokartg, It is that "dmesg.txt" which is missing numbers all over the place.20:34
rtgfoka: how about once its booted? do the consoles work ok?20:35
fokartg, You're referring the Ubuntu report reported by a Dell engineer, right?  :-)20:35
rtgfoka: yeah, its a dell box.20:35
fokartg, Well you see, I couldn't get it to boot further because it some how messed up the SATA driver.20:35
rtgwhich is exactly where Torsten ended up. 20:36
fokartg, With the LAN disabled, however, I could get into GNOME and all, and once there, dmesg is not missing anything.20:36
rtgmaybe the problem clears up after we fix the r8169 crash.20:36
fokartg, Yes, I hope so too.  It is weird because it appears that only "every second numbers" are missing.20:37
rtgwell, who knows what the side effects of memory corruption are. I'll produce a PPA kernel later (maybe tonight0 with this fix.20:38
fokartg, This may not be the exact rule:  Whenever there are two of [0-9] in a row, the second digit gets dropped out.20:38
fokartg, Nice!  Thank you very much!  :-)20:39
ivoksummm...20:40
ivokswhy don't we just apply this?20:41

rtgBenC is the dapper dude.20:42
BenCrtg: Thanks, you're pretty dapper yourself20:43
alex_joniheh20:43
fokartg, I just looked at Torsten's package (very briefly), and I saw that he did applied  "[PATCH] NET: r8169: fix oops in r8169_get_mac_version" (http://lkml.org/lkml/2008/4/17/298)20:43
rtgho ho ho20:44
fokartg, Looks like that's the cause.20:44
BenCfoka: Ah, right, that's the crash TeTeT is seeing20:44
ivoksBenC: :) ok, so how about it? :)20:44
rtgfoka: yep - I've come to the same conclusion. I'm preparing an SRU inclusion request.20:45
fokartg, While googling randomly, I saw another patch: http://www.spinics.net/lists/netdev/msg60658.html  , I wonder if it may come in handy too?  :-)20:45
BenCivoks: We sure can, but that bug is triggering some memories...does it cause a regression in another area?20:45
ivoksBenC: it's part of 2.6.17, if i'm not mistaken...20:45
ivoksi don't know about regressions20:45
BenCivoks: does it apply cleanly to our 2.6.15 tree?20:45
rtgfoka: one thing at a time. In order for it to satisfy SRU policy, it has to be reproducible, testable, yada, yada.20:46
BenCI think it may have huge rejects because of some CVE's we also fixed20:46
fokaBenC, Yes, we experienced the same bug on a desktop motherboard here too.20:46
ivokswell, this patch was against our tree20:46
ivoksBenC: i can check, of course...20:46
BenCfoka: I believe I already told TeTeT about that bug, I tracked it down, and it was triggered because the 8169 mac is unknown (but that's not the bug)20:46
BenCfoka: Any chance we can get correct info for that mac in addition to the fix?20:47
fokartg, True.20:47
fokaBenC, Unfortunately, we have returned the motherboard, but I'll ask my colleague to borrow it again tomorrow.20:48
BenCfoka: thanks20:48
fokaBenC, Should I create a bug report on Launchpad?  (I see that there is already https://bugs.launchpad.net/bugs/223656 , but it is a "private" bug?  I finally got sneaky and managed to get a Google cache of it... :-p)20:49
rtgfoka: oh, you bad boy :)20:50
BenCfoka: Really?!20:50
BenCI wonder if it was public for a bit, or if there's some other bug that let google do that20:50
fokartg, Not any more, now Google cannot find the cache.  :-D20:51
rtgfoka: yeah - he marked it private.20:51
fokartg, But it was the only relevant result when I searched "rtl8169_init_one ubuntu" or "rtl8169_init_one 8.04" or something like that.20:51
fokartg, I don't know how Google got through either.  Maybe it got the cache before he marked it private?  Or Google got a special account or something like that?20:51
rtgfoka: I'll see if I can get him to open it up. there isn't anything particularly proprietary. In fact, his help came from a public source (i.e. you).20:52
ivoksBenC: it fits in dapper git as a hand in a glow20:52
BenCivoks: I hope you mean glove20:52
ivoksright :)20:52
fokartg, Or should I just start a new bug report?  :-D20:53
rtgfoka: no, gimme a bit. any new one would just get marked as a duplicate. 20:53
fokartg, Gotcha.  :-)  That nicely justifies my procrastination.  :-)20:54
* foka has never filed a bug report on Launchpad before. :-)20:55
rtgfoka: yeah, all that paper work, such a pain in the ass. you ought to do a bunch of SRUs. very tedious.20:55
* foka goes read up about SRUs20:58
fokartg, I got a dmesg.txt (with missing numbers here).  Would you like a copy?  (Or should I just wait until the bug becomes public and attach it to the bug report then?)20:59
rtgfoka: some light reading https://wiki.ubuntu.com/StableReleaseUpdates21:00
rtgfoka: as for the dmesg output, its garbled because of memory corruption.21:00
fokartg, Yes, I'm on that page.  :-)21:00
rtgif it continues after the r8169 fix, then we'll have to figure out why.21:00
fokartg, I see.  Thanks!21:00
fokaBenC, Just to make sure I understand you correctly.  MAC addresses look VV:VV:VV:PP:PP:PP, where VV:VV:VV represents the vendor (like RealTek).  You mean the bug is caused by new network chip containing VV:VV:VV  that is not listed in the latest r8169 driver, is that right?21:02
fokaBenC, So, what I should do once I get the motherboard back, is to boot up e.g. Ubuntu 7.10 LiveCD, look at "ifconfig" output, and report back to you what the MAC address is.  Is that correct?21:05
noelferreiramy keys get stuck sometimes and other times don't work. can anyone help me with this huge bug: http://pastebin.com/m7bc8805221:10
rtgfoka: correct, VV:VV:VV is the vendor part of the MAC address and should not be zero.21:11
rtgfoka: but that code isn't looking at the MAC address, its looking the revision of the MAC processor.21:12
rtgfoka: however, it does look like the current Hardy driver will FUBAR on an unknown MAC version.21:15
rtgwhere MAC version is the same as chip revision or model.21:15
fokartg, I see, thanks!  Is there an easy way to get the MAC version (or whatever info you need) from the command-line?  Or should I test by playing with r8169.c source code?21:16
fokartg, Hmm... is that revision number written on the chip itself?  I think I took a photo of the chip... let me try to dig it up...21:17
rtgfoka: yeah - you'll have to instrument the code. The ID on the chip migh give you an indicator of the revision or model.21:18
rtgsometimes those numbers are just a cross reference in a parts catalog21:18
rtgfoka: test kernel building at https://edge.launchpad.net/~timg-tpi/+archive. Use 2.6.24-17.32ubuntu7 or higher21:24
fokartg, I see.  Thanks!  I finally found the picture.  Here is what is written on it:  RTL8102E // 8Z121S1 G807B21:26
fokartg, Many thanks about the link!  I'll make note of it.21:26
rtgfoka: if you look in the driver code for 'enum mac_version' you can see there isn't an 8102E, so I'm betting you'll still have problems.21:28

rtgmdomsch: can you comment on bug #225811 ? Steve is asking for SRU justification, so perhaps I didn't get the explanation correct.21:33
mdomschrtg, I did21:37

cradekwhat's the launchpad bug report number?23:16
noelferreirai don't know cradek23:16
cradekfiling one, if you can't find one when you search, would be the best way to get this worked on23:19
cradekin the bug report, I suggest also saying what basic debugging you have tried, like a new keyboard, usb vs ps2, etc etc.  you will get a lot more attention that way.23:21
noelferreiraok 23:22
