Shred00i built an upstream (kernel.org) kernel with the lucid .config but /sbin/init starts but doesn't do anything04:56

Shred00initctl: Did not receive a reply.  Possible causes include: the remove application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.04:57

ricotzdoes somebody know if this commit is proposed for 2.6.38.x yet? http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=243b422af9ea9af4ead07a8ad54c90d4f9b6081a11:09
diwicricotz, since it's cc:ed stable it's very likely to be in 2.6.38 sooner or later11:17
diwicricotz, if you want it sooner, write an email to the kernel-team@lists.ubuntu.com ML with a subject line starting with "UBUNTU: (pre-stable) Natty"11:18
diwicricotz, if you want it sooner in Ubuntu, i e11:18
ricotzdiwic, ok11:20
diwic....and explain why it's important11:21
ricotzas the commit says - currently using aio is broken in natty11:21

bullgard4'~$ uname -a; Linux T42 2.6.38-7-generic #39-Ubuntu SMP Fri Mar 25 19:38:02 UTC 2011 i686 i686 i386 GNU/Linux'. I have had at least 3 messages "panic occurred, switching back to text console". I could do nothing but restart the computer. I did not find this reflected in dmesg or syslog. How can I contrubute with a meaningful error report?12:31
Krunchbullgard4: there should be a full panic message on the console at the time of the problem, that would be helpful12:33
Krunchbullgard4: you can have it sent to another box over the network with something like netconsole12:33
bullgard4What do you mean by "on the console"? I had available at that time only one virtual console. As I already wrote, I could not call any other program, not even "netconsole". 13:27
Krunchbullgard4: netconsole is something you set up before the problem happens13:28
Krunchbullgard4: the console as in /dev/console, by default it's the first virtual console but you can change that for the serial console for example13:28
bullgard4Right. But I did not know beforehand that this would happen. Thus I did not set up netconsole.13:29
Krunchbullgard4: yeah so there is nothing we can do about your past panic but you can set up your system to collect relevant data next time it happens13:29
bullgard4Krunch: How should I set up this computer now in order to prepare it for collecting relevant data if a panic occurs next time?13:31
Krunchi don't know much about ubuntu so i can't be very specific but look into netconsole and kdump13:32

hggdhJFo, smb: no, I was stating that manually running KVM on a natty install running a Maverick kernel seems to work16:51

smbhggdh, Not sure I *want* to know what is in there. Ah ok16:51
hggdhthis was a test jj asked me to run16:51
tgardnerogasawara, I created a master-next branch in oneiric so I can start dribbling crap in your pristine kernel.16:51

ogasawaratgardner: I'm still hammering out armel build failures16:52
tgardnerogasawara, which is why I wanted to stay out of your way16:52
ogasawaratgardner: anything else you want to shove into natty?  I'm gonna prep an upload for after our meeting.16:53

vishhi, I'm trying to test upstream kernel for Bug #733392 , but only able to find 2.6.35-rc1-lucid and cant see any 2.6.35-rc1-maverick, is that something I need to consider, or is 2.6.35-rc1-lucid OK too?17:20

ogra_JFo, linux-ti-omap ?? are you meaning to say omap4 there ?18:02
* ogra_ doesnt want to interrupt the meeting, we dont have linux-ti-omap anymore18:03
JFolinux-ti-omap is the package name I am looking at. Has that changed to omap4 package name?18:03
ogra_in natty we dont have a linux-ti-omap source package anymore18:04
ogra_we have a linux-ti-omap4 package since maverick 18:04
ogra_and still have it18:04
ogra_(just to make sure you actually look at the used packages :) )18:05
ogra_https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4 is what we care for in natty (for omap4), for omap we plainly use the linux package 18:06

brycehJFo, heya20:09
brycehJFo, bug #686388 could really use some kernel team lovin' about now.  This seems to be at the root of a collection of gpu lockups the kernel is experiencing, and upstream has a couple patches that require testing before they're going to put them in.20:10
brycehJFo, I probably sound like  a broken record.  "This is the most important gpu lockup ever, and... patches!"20:11
JFoheh20:11
JFono sweat20:11
brycehanyway, if you could bump the above bug up in the priority a bit, it could potentially help eliminate a bunch of the gpu lockup bugs20:12
JFook, let me see what I can do20:12
brycehJFo, I think having a test kernel built of intel-drm-staging would be the right next action for the bug; then we can have users test that and give upstream feedback20:13
bryceh(yes, upstream has yet another drm testing branch...)20:13
JFoheh20:13
brycehhttp://git.kernel.org/?p=linux/kernel/git/ickle/drm-intel.git;a=shortlog;h=refs/heads/drm-intel-staging20:13
tgardnerbryceh, would a PPA test kernel work for you?20:14
brycehtgardner, yep20:16
brycehtgardner, just something for reporters to load and test20:16
tgardnerbryceh, those 2 patches against natty, right?20:17
brycehtgardner, yes20:17
sforsheetgardner, bryceh, I think there was some discussion on lkml about one of those patches possibly causing a regression, a third patch might also be needed20:32
sforsheelet me see if I can dig up the thread20:32
brycehsforshee, I gather one of the two patches fixes a regression that the other patch opens, so the two go together.  Thanks for doublechecking the thread.20:34
