Bug Description

On my ThinkPad T510, raring’s kernel 3.7.0-2-generic crashes on suspend, leaving a black screen with the power light blinking. (It works in quantal’s kernel 3.5.)

[Rereporting from kernel 3.7, to try to get more relevant information from apport.]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.7 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I'd also like to perform a bisect to figure out what commit caused this regression. It would be very helpful to know the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.

Can you test the following kernels and report back? We are looking for the first kernel version that exhibits this bug:

v3.5.7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5.7-quantal/
v3.6 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/
v3.7-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.7-rc3-raring/

You don't have to test every kernel, just up until the kernel that first has this bug.

Thanks in advance!

I assume the “Won’t Fix” status is due to an error in the automated script, can you please remove it?

@Andres Kaseorg,

Yes the wont fix status was due to an error.

I started a kernel bisect between upstream v3.6 and v3.7-rc1. The bisect will require testing of about 10 - 12 kernels. I built the first test kernel, which is up to commit:

Can you test this latest kernel and report back if it has the bug or not?

Anders Kaseorg (andersk) wrote :

The bug seems config-dependent, since if I compile Ubuntu-3.7.0-3.9 with defconfig, the resulting kernel can successfully suspend from the initramfs, while linux-image-3.7.0-3-generic cannot.

Anders Kaseorg (andersk) wrote :

I started randomly hybridizing the working and failing .configs, and bisected the problem down to this difference:

--- bad4 2012-11-27 07:52:28.535253255 -0500
+++ good6 2012-11-27 07:35:58.376369630 -0500

That is, if I turn off CONFIG_LOCKUP_DETECTOR, suspend starts working again.

Joseph Salisbury (jsalisbury) wrote :

Thanks for testing and providing this information.

I see that CONFIG_LOCKUP_DETECTOR is enabled in Precise(12.04) and Quantal(12.10) as well as Raring(13.04). Do you also see this bug on those releases?

However, I do see that Raring is the only release that has CONFIG_HARDLOCKUP_DETECTOR enabled.

I'll build a Raring test kernel with CONFIG_HARDLOCKUP_DETECTOR disabled and post a link to it.

I’m in the middle of a commit bisect now, and one of the suspicious commits is the same one mentioned here:
which has a reply with a patch.

Confirmed that bcd951cf10f24e341defcd002c15a1f4eea13ddb is the first bad commit, that tglx’s patch in the above LKML thread fixes it, and that removing nmi_watchdog=0 from my kernel command line is a workaround (oops).

Joseph Salisbury (jsalisbury) wrote :

That's great news, Anders. I responded to the thread you posted in comment #16 to see if this patch will be submitted for v3.8.

Joseph Salisbury (jsalisbury) wrote :

The patch will be included in v3.8 and applied back into v3.7 stable:

I'll mark this bug back to triaged for now. It would be great if you can test once this patch lands and report back if it fixes this bug for you.

Thanks again for the great work!

The referenced patch landed in 3.7, so let's assume that this bug is fixed.
