Jaime, maybe you have a wired setup and can try to set it up?

Jaime, are you running virtualbox or some other virtualization software?

I'm quite sure that this relates to running virtualbox - the system crashes within 5 minuttes. Not running virtualbox does not make the system unstable.

The diff does not reveal any huge differences between lowlatency and generic, but looking at it maybe others can gen an ideas as to wht might be causing this all-over-the-place panic.

Apparently CONFIG_IRQ_FORCED_THREADING_DEFAULT is not an upstream config flag.

The resulting param force_irqthreads is not set no true unless "threadirqs" are on the kernel commandline.

In the problematic kernel it is set to true by default - something that will never happen on a vanilla kernel.

It can be turned off using "nothreadirqs" on the commandline - which is exactly what I'm going to try now.

Well - nothreadirq has the effect that my virtualbox crashes. Someway around the time where I would expect the whole system to crash.

Jaime - I thing adding "nothreadirqs" would be something that you should try also.

  been solved in 3.13. Unfortunatly it seems like it is not.

I will add crashdumps when I get crashes that do not just lockup the
machine but currently I have only seem complete lockups with 3.13

So the essense is :

3.11-lowlatency crashed 10 time today most of the crashes reached the console so I could see the panic text.
3.13-lowlatency crash 1 time 10 minuttes after first boot. No VT swtich. During next reboot it also locked.

Title:
  lowlatency-flavour crashes and locks up alot

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The 3.11 flavour that where upgraded to 3.13 today crashed 10 times
  this morning. I have the crashdums, but I figured that it might have
  been solved in 3.13. Unfortunatly it seems like it is not.

I will add crashdumps when I get crashes that do not just lockup the
  machine but currently I have only seem complete lockups with 3.13

So the essense is :

3.11-lowlatency crashed 10 time today most of the crashes reached the console so I could see the panic text.
  3.13-lowlatency crash 1 time 10 minuttes after first boot. No VT swtich. During next reboot it also locked.

I built an amd64 lowlatency test kernel with PREEMPT disabled. This kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1275116/

Can you test this kernel and see if it also exhibits this bug? Please note, this is a diagnostic kernel and not a fix.

Thanks in advance!

I don't know what changes has gone into the trusty 3.11 or 3.12 kernel. but if I should bisect based in "threadirqs" I would make 3.12 as good and 3.13 as bad based on my comment from yesterday :

<quote>
v3.12-trusty/ seems to work for me. So to me it seem to have broken between 3.12 and 3.13. For sure it did break since where saucy where around christmas, because I ran that with it's lowlatency until then.

There is some other bug reports that indicate this may be fixed in the mainline kernel. Can you see if that is the case by testing 3.14-rc4:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc4-trusty/

If the bug still exists there, then the other bug report may not be related.

If 3.14-rc4-lowlatency is as good to set with "threadirqs" as the generic kernel I can say that 3.14 works as a charm.

That is good news that the bug appears to be fixed in 3.14-rc4. If it is stable and the bug is in fact gone after some time, we can perform a reverse bisect to identify the commit that fixes this in 3.14-rc4.

@jamie, it should be ok that HDMI is not working with this kernel. We are only interested in testing it to identify the commit that fixes this original bug. Once we find the fix, we will backport or cherry pick it into Trusty.

Can you test this kernel and confirm it resolves this bug? I built an i386 and amd_64 version of the kernel. You will need to install both the linux-image and linux-image-extra packages.

Per comments #167 and #168, it sounds like this bug is resolved in v3.14-rc4. It also sounds like commit a1227f3c is not what fixes this. It is probably best for us to perform a reverse bisect to identify the real commit that fixes this in 3.14. The first step is to identify the first 3.14 kernel version that fixes the bug. We know 3.14-rc4 has the fix, so can you test 3.14-rc3:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc3-trusty/

If v3.14-rc3 also has the fix, then we would want to test 3.14-rc2, etc until we find the first kernel that exhibits the bug again.
