Description Jérôme 2016-09-15 20:11:19 UTC
Created attachment 126563 [details]

My system froze. I waited a few minutes but nothing happened. I could not "Ctrl+1", I had to REISUB.

I'm running a Debian Jessie with a Radeon R7 240 GPU

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240]
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde/Pitcairn HDMI Audio [Radeon HD 7700/7800 Series]

using the free radeon driver (xserver-xorg-video-ati (1:7.5.0-1)) and a recent kernel:

4.6.0-0.bpo.1-amd64 #1 SMP Debian 4.6.4-1~bpo8+1 (2016-08-11) x86_64 GNU/Linux

Attaching log excerpt.

Since it only happened once, I'm not sure there's much we can do with this.

I'm not even sure this is the right place to report this.

If there's anything useful I can get via ssh from another machine when it happens, please tell me.

Comment 1 Michel Dänzer 2016-09-16 08:31:23 UTC
It looks like the GPU hangs. Please attach the corresponding dmesg output as well, captured after the problem occurred, and the output of glxinfo.
Comment 2 Jérôme 2016-09-16 08:38:58 UTC
OK, if this ever occurs again, I'll try to SSH from another machine and get both dmesg and glxinfo outputs.
Comment 3 Michel Dänzer 2016-09-16 08:46:18 UTC
You can get the glxinfo output anytime FWIW.

Comment 5 Michel Dänzer 2016-09-21 02:11:18 UTC
If it happens again, any chance you can try a newer version of Mesa?
Comment 6 Jérôme 2016-09-21 07:32:43 UTC
I suppose I should get a new version of Mesa before it happens again.

I'm currently using Debian Jessie. If there is a more recent version available in the repos (backport, or even compatible package in testing), I don't mind.

I can also move to testing if required.

Please point me to the right package or set of packages.

Comment 7 Paul Wise 2016-09-21 08:49:01 UTC
There is a newer version of mesa in Debian jessie-backports:


This command should upgrade all the mesa packages you have installed:

aptitude -t jessie-backports upgrade '?source-package("^mesa$")~i'
Comment 8 Jérôme 2016-09-22 13:44:35 UTC
Done. Thanks for the command line.

aptitude -t jessie-backports upgrade '?source-package("^mesa$")~i'

Comment 9 Jérôme 2017-01-10 22:51:47 UTC
In case that matters, I just discovered the driver needs a proprietary firmware which was not installed.

There's no evidence of missing microcode in the files attached to this report.

Did the freeze occur again?

I discovered that while investigating https://bugs.freedesktop.org/show_bug.cgi?id=99337

From what I understand, due to this, I was not even using radeon but a generic fallback driver... So it wouldn't be a radeon issue.

> Did the freeze occur again?

A few freezes occurred (2, maybe 3) but I can't tell if those were due the same cause. I didn't have the time or available secondary machine to get necessary info (ssh log from another machine, demsg, glxinfo) when it happened.

I'm closing this for now as "NOTOURBUG". I'll reopen if it occurs again and I can get necessary info (Xorg log, dmesg, glxinfo).
