[Kernel-packages] [Bug 1011914] Re: BUG: soft lockup - CPU#0 stuck for 23s! [kworker/0:3:566]; RIP: 0010:[ffffffffa00c9d73] [ffffffffa00c9d73] mei_timer+0xc3/0x260 [mei]
I am facing something similar. I am already struggling with an issue on this
Tyan S3970 (Ubuntu 12.04.03 fully updated), which I am in the process of
reporting here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1217229
I have a pair of system disks (raid/luks) which I am able to boot. I
have a pair of data disks (raid) which, when attacked to the sata
controller (along with the system disks) lead to a boot failure and
drops me into busybox. When I hit control-d to continue the boot, I get
stuff that looks like:
BUG: soft lockup - CUP#7 stuck for 23s! [kworker/7:0:469]
BUG: soft lockup - CUP#7 stuck for 22s! [kworker/7:0:469]
INFO: rcu_sched self-detected stall on CUP { 7} (t=15000 jiffies)
INFO: rcu_sched detected stalls on CPUs/tasks; { 7} (detected by 2, t=15004
jiffies)
INFO: Stall ended before state dump start
I have posted pictures of my screen. The first pic is of one boot. The second
pair is of a second boot, both using Ctl-D from busybox:
https://www.dropbox.com/sh/whypnvtkzkdyx3p/u3bnQQBqjb
One more piece of information: When I first booted with all 4 disks
attached (zero'th boot, if you like), I was successful. I tried to
mount the data disks and got a degraded array. That was odd, as I
checked and the disk health was reported as good/healthy for both disks.
Also, I had been watching the disks and there has been no sign of either
disk developing problems. It's when I shut down and rebooted that I
found myself getting dropped into busybox and took the first picture.
More information on my machine is located at the above bug report.

Pachy, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ . If it remains an issue, could you please run the following command in the development release from a Terminal (Applications-Accessories-Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux replace-with-bug-number Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: kernel-fixed-upstream-v3.5-rc2-quantal ** Tags added: bios-outdated-a09 kernel-fixed-upstream-v3.5-rc2 ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1011914 Title: BUG: soft lockup - CPU#0 stuck for 23s!
