[HP ProBook 4520s Notebook PC] Keyboard stops working after S3 3.11 regression

[David Henningsson]

After S3 on this laptop, the keyboard is completely non-responsive. (E g, Ctrl-Alt-F1 does not work) The trackpad is still working though.

I believe this is a kernel problem because
 1) It started happening recently, i e, it was not a problem when running with a 3.10 kernel.
 2) I can't find *any* keys working, not even magic keys (REISUB)

David Henningsson, as per http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome/?sp4ts.oid=4145326&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3DswEnvOID%253D4059%257CswLang%253D%257Caction%253DlistDriver&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken#BIOS an update is available for your BIOS (F.21). If you update to this, does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

Thank you for your understanding.

Mainline kernels tested so far:
3.10.10 - not buggy
3.11-rc1 - not buggy
3.11-rc7 - buggy

[David Henningsson (diwic)]

3.11-rc3 - not buggy
3.11-rc4 - not buggy
3.11-rc5 - not buggy

[David Henningsson (diwic)]

Sorry, turns out 3.11-rc3 and 3.11-rc5 are buggy as well, it's just more difficult to reproduce than expected, because it does not happen every time.

[David Henningsson (diwic)]

And also found the bug on 3.11-rc1 now, although it took a while to reproduce.

[Joseph Salisbury (jsalisbury)]

Does the bug exists on 3.10 final:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10-saucy/

If not, we can bisect between v3.10 and v3.11-rc1.

It might also be worth giving 3.11 final a spin:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-saucy/

[David Henningsson (diwic)]

@Joseph,

I was running 3.10.10 yesterday and didn't experience the bug, so I *think* it's safe. Btw, do you have any script or documentation on how to do a git bisect (in combination with Ubuntu packaging)? If so I can probably do the bisect myself.

[Joseph Salisbury (jsalisbury)]

@David,

There is some documentation on bisecting at:
https://wiki.ubuntu.com/Kernel/KernelBisection

I could also help with the bisect by building kernels if you need.

[Joseph Salisbury (jsalisbury)]

Given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We are approaching release and would like to confirm if this bug is still present. Please test again with the latest development kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get dist-upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

Thank you for your help, we really do appreciate it.

[David Henningsson (diwic)]

kernel 3.11.0-8.15 confirmed *bad*, i e bug present.

[David Henningsson (diwic)]

Okay, let's see how this will work out...

$ git bisect start
$ git bisect good v3.10
$ git bisect bad v3.11-rc1
Bisecting: 4921 revisions left to test after this (roughly 12 steps)
[1286da8bc009cb2aee7f285e94623fc974c0c983] Merge tag 'sound-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

[David Henningsson (diwic)]

Seems I can't reproduce the bug on that kernel.

$ git bisect good

[1b375dc30710180c4b88cc59caba6e3481ec5c8b] mutex: Move ww_mutex definitions to ww_mutex.h

[David Henningsson (diwic)]

Reproduced, but on 5th attempt, so I'm suddenly unsure if the last one was good, because I only tried five times...

$ git bisect bad
Bisecting: 1051 revisions left to test after this (roughly 10 steps)
[899dd388853071f5c8848545209d4e2c5d95b1d9] Merge tag 'for-linus-3.11-merge-window-part-1' of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs

[penalvch (penalvch)]

David Henningsson, if it wouldn't be too onerous, I would just mark it bad if you can't suspend/resume 30-50 times.

[David Henningsson (diwic)]

Can't reproduce with kernel on step 3.

$ git bisect good
Bisecting: 463 revisions left to test after this (roughly 9 steps)
[5b0207bb59b26a8cb5b53f13c99c67eb0d2a7abb] Merge branch 'drm-next-3.11' of git://people.freedesktop.org/~agd5f/linux into drm-next

[David Henningsson (diwic)]

While waiting for the next kernel to compile, I also tested 3.12-rc2, which failed at the first attempt. I e, still present upstream.

[David Henningsson (diwic)]

Step 4 is good too, I hope...

$ git bisect good
