zulBenC: ping got a couple of minutes12:51
zul?12:51
BenCzul: Just a little12:52
zulsure so what should we do for the xen kernel?12:52
zulsince there isnt going to be paravirt-ops12:52
BenCzul: I'm thinking unless something amazing happens, you should probably keep linux-source-2.6.17 around to build xen with12:53
zulyeah thats going to be a problem since udev doesnt like 2.6.17 under fiesty12:53
BenCwe want to keep it in sync with one of our tarballs, but it looks like that wont be 2.6.2012:53
BenCmaybe we can talk to Keybuk about some edgy compatibility in udev12:54
zulsure..12:54
zuli can try with 2.6.20 as well12:54
KeybukBenC: ?12:54
zulBenC, well let me try with 2.6.20 before we pull the trigger 12:56
BenCKeybuk: Some people are saying that feisty udev + edgy kernel == badness12:56
KeybukBenC: should work fine, unless they need ide-generic12:56
zulmore like udev initramfs-tools badness12:56
BenCedgy initramfs-tools?12:56
BenCmaybe explains the problem12:57
zulyeah spits out a warning12:57
Keybukah, hmm12:57
Keybukactually udev requires 2.6.1912:57
Keybukin feisty12:57
Keybukso initramfs-tools will refuse to make the initramfs12:57
zulmeh..12:58
zulok ill try to head to 2.6.20 then12:58
ajmitchKeybuk: yeah, I've already had issues with trying to test xen updates, a bit of a pain12:59
zulbald is what ill be then ;)12:59
Keybukajmitch: the pain is outweighed against the pain of trying to guess anything that could break in 2.6.1712:59
ajmitchkids will do that to you :)12:59
kylempfft, just buy more hardwar.12:59
kylemto hell with this virtualization stuff.12:59
Keybukkylem: ENOMONEY12:59
zulkylem: ditto ENOMONEY01:00
kylemjust stop buying food01:00
zulwell redhat looks like its doing 2.6.19 maybe that could be a happy medium01:00
kylemGAH01:00
kylem6391 N Jeannette Mcgra Jeannette check this.01:00
zulkylem: yeah im fat enough01:00
kylemeverytime i add to my .procmailrc, they change the damn thing01:01
Keybuktbh, I'd be really unhappy supporting divergent kernels01:01
Keybuke.g. if we go ahead and do the user-space binding in feisty01:01
Keybukthen udev will be relying on that01:01
Keybukwhich won't work if you ran 2.6.19+xen01:01

lifelessxhaker: I think BenC wants to know what was odd03:55
xhakerBenC, sorry I was filling a bug report about it. You can read it here. I assigned it to Colin Watson. But you should see it. since it is kernel related also03:55
xhakerhttps://bugs.launchpad.net/distros/ubuntu/+bug/7459203:55
xhakerlifeless, ;)03:55
BenCyou shouldn't assign it till it's confirmed03:56
xhakerBenC, I didn't realize. I was trying to get colin's attention though.03:56
BenCok, none of that is a kernel bug03:57
BenCthe hda->sda thing is because we are switching from ide to ata modules..ata uses the scsi subsystem03:58
BenCxhaker: Some of those issues may be know, so you may want to search debian-installer reports03:59
xhakerBenC, my hard drive isn't scsi? :( joke03:59

AnAntBenC: ping05:09
BenCAnAnt: yo05:10
AnAntBenC: I am using Edgy, and I found out that it doesn't support SD cards05:10
BenCAnAnt: That's correct05:10
AnAntBenC: although in dapper it did05:10
BenCare you sure?05:10
AnAntBenC: well, let me correct this05:11
AnAntwhile Edgy was still beta, I used Dapper's kernel05:11
AnAntbut I applied a 2 line patch to support > 1GB cards05:11
AnAntand some colleage lent me his SD and I used it with that kernel (which was only patched to support >1GB cards) and it worked05:12
AnAntI will try it again later today to make sure though05:12
AnAntas I still have that kernel here05:12
=== tonyyserver [n=anthony@d235-240-148.home1.cgocable.net] has joined #ubuntu-kernel
lifelessBenC: I have a SD card - or at least its ~ that form factor :) and it worked on dapper, edgy and fisty05:13
AnAntwhat's ~ ?05:15
BenCaround/about05:15
lifelessits a sdcard slot, but it may be a less-proprietary card is what I mean05:15
AnAntoh05:16
AnAntBenC: btw, the SD card was a Transcend SD card05:16
BenCAnAnt: Are you using it in the same type hardware slot?05:17
BenCthe card isn't as important as the hardware you are reading it with05:17
AnAntBenC: yeah, that TI slot05:17
AnAntBenC: in my laptop05:17
BenCusing the mmc driver?05:17
lifelessBenC: is mine relevant, I can give details05:17
AnAntTexas Instruments PCI6411, PCI6421, PCI6611, PCI6621, PCI7411, PCI7421, PCI7611, PCI7621 Secure Digital (SD) Controller05:17
AnAntBenC: well, dunno which driver I use, it auto-detected 05:18
BenClifeless: Is it usb, or mmc?05:18
AnAntBenC: I recall there was another module with mmc that is loaded05:18
BenCAnAnt: Yeah, check in /lib/modules/`uname -r`/kernel/drivers/mmc/05:19
AnAntBenC: there's sdhci there (in the dapper's kernel)05:19
lifelessBenC: mmc05:19
lifeless02:01.2 Generic system peripheral [0805] : Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 17)  0805: 1180:082205:20
AnAntlifeless: I think sdhci was loaded too, anyways, I'll try again when I go to work today05:20
lifelessAnAnt: it neds to be if its going to work ;)05:21
AnAntBenC: btw, is there any simple article about the difference between CONFIG_PREEMPT, and CONFIG_PREEMPT_VOLUNTARY ?05:21
AnAntBenC: also sometimes I get a message saying something about "underrun", what's that ?05:22
BenCAnAnt: voluntary is where preempt is done when the kernel calls yield()05:22
BenCPREEMPT is real preemptibility05:22
AnAntBenC: well, I followed the thread about PREEMPT in devel, I don't care about sound, but I run simulations, and CONFIG_PREEMPT in dapper made them fast indeed05:23
AnAntBenC: but I'm not sure if VOLUNTARY in edgy made it slower05:23
BenCAnAnt: Then the lowlatency kernel is what you'll want05:23
AnAntseems I got to test it05:23
AnAntBenC: ok, thanks05:23
AnAntdoes the "underrun" have to do with the voluntary thing ?05:24
AnAnt?05:32
AnAntBenC: does the "underrun" have to do with the voluntary thing ?05:32
BenCprobably05:42
AnAntthanks05:42
AnAntoh, what's the sky2 bug? is it skype related?05:42
