[DH77EB] Regression: Intel graphics fails when bringing monitor out of sleep

[Jussi Pakkanen]

Bug 1135668 asks for a regression bug to be filed in case the update does not fix the issue.

It doesn't. Thus this bug report.

This change was made by a bot.

[Joseph Salisbury (jsalisbury)]

The patch that should have fixed bug 1135668 was released in 3.8.0-17:

git describe --contains 83e06af
Ubuntu-3.8.0-17.27~99

Was bug 1135668 never resolved?

[Jussi Pakkanen (jpakkane)]

I tried the upstream kernel and could not reproduce the issue by making the monitor sleep 10 times in a row. The standard Ubuntu kernel has been broken all the time (though the issue only manifests every now and then).

So either that patch alone is not sufficient or I just had poor luck in trying to reproduce the bug with an upstream kernel.

[Joseph Salisbury (jsalisbury)]

Can you post the upstream kernel version you were testing and could not reproduce the issue?

Also, 3.8.0-25.37 is not in Raring proposed. It might be worth while to test -proposed to see if the issue exists there.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Jussi Pakkanen (jpakkane)]

The kernel was whatever was in intel-drm-nightly on the sixth of March. I don't remember the exact version.

I have had proposed enabled on this machine for quite some time. I only filed this bug after verifying that proposed did not fix the issue.

[Joseph Salisbury (jsalisbury)]

Are you now running 3.8.0-25.37 and still see the bug? I see the bug was opened with kernel 3.8.0-23.34.

[Jussi Pakkanen (jpakkane)]

It is still there.

[Joseph Salisbury (jsalisbury)]

Can you also test the 3.8.13.2 kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.13.2-raring/

[Jussi Pakkanen (jpakkane)]

Tested. The issue happens with that kernel, too.

[Joseph Salisbury (jsalisbury)]

Do you see this bug with the intel-drm-nightly builds newer than the sixth of March kernel? Or are you saying the bug does not happen with any intel-drm kernels newer than the sixth of March?

[Jussi Pakkanen (jpakkane)]

I have not tried drm-nightly kernels after the third of March. What probably happened was that the bug was present in that one too, it just did not manifest during that test (I tested suspend 10 times in a row, which usually is enough to trigger the bug).

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest Intel DRM kernel, which can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2013-06-24-saucy/

[Jussi Pakkanen (jpakkane)]

With that kernel I can't reproduce the bug. I tried over 20 times.

[Joseph Salisbury (jsalisbury)]

Can you also test the latest mainline kernel to see if the fix is there yet:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.10-rc7-saucy/

[Jussi Pakkanen (jpakkane)]

With that kernel the bug does not appear.

uname -a
Linux demolition 3.10.0-031000rc7-generic #201306221735 SMP Sat Jun 22 21:35:55 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

[Jussi Pakkanen (jpakkane)]

Scratch that, I just managed to reproduce it with 3.10.0-031000rc7.

There was a difference, though. In earlier versions the system changes to a lower resolution and moves windows around so they are on different virtual desktops than earlier. Some are maximised, too. In this crash the resolution switch did not happen but windows were still shuffled around as if it had happened.

This is in dmesg:

[ 8579.127001] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 141

[Joseph Salisbury (jsalisbury)]

The v3.11-rc1 kernel is now available. Can you test that kernel to see if the fix made it into mainline yet:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy/

[penalvch (penalvch)]

Jussi Pakkanen, as per https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Desktop+Boards&ProductLine=Intel%C2%AE+7+Series+Chipset+Boards&ProductProduct=Intel%C2%AE+Desktop+Board+DH77EB an update is available for your BIOS (0101). 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

Thank you for your understanding.

[Jussi Pakkanen (jpakkane)]

The BIOS update does not help. Here's the output:

EBH7710H.86A.0101.2013.0516.1649
05/16/2013

I'll try the new mainline kernel soon, hopefully tomorrow.

[Jussi Pakkanen (jpakkane)]

I could not reproduce on 3.11, but given how tricky this has turned out to repro, I can't really guarantee that it is properly fixed.

[penalvch (penalvch)]

Jussi Pakkanen, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, 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>

[Jussi Pakkanen (jpakkane)]

Instead of that I just upgraded to Saucy. I have not been able to reproduce this issue thus far. It may very well have been fixed. But as this is a nondeterministic bug one can't be sure.

If the issue does not happen in the next few days, I'll mark this issue closed.
