dmesg output with the message of a kernel hang
Hi.
I have recently (say, since upgrading to kernel 4.2, but not really sure of the
exact period) having some GPU hangs with my Sandy Bridge notebook while using X
and, during these events, all the user interface elements become frozen for a
few moments.
In one occasion, I even had my entire X session killed and I was back to the
Linux console.
I *believe* (but can't say with 100% confidence) that it happens when I play
videos on Youtube with Debian's Iceweasel. I don't believe that I have
experienced one of these hangs with "regular" video players like mpv, mplayer
or vlc, but my memory is really weak these years.
I am attaching some information and, if needed, I can try to provide anything
else that you ask me to.
Output of uname -a:
* Linux zatz 4.2.0-1-amd64 #1 SMP Debian 4.2.6-1 (2015-11-10) x86_64 GNU/Linux
Distribution:
* Debian testing.
Machine:
* It's (I believe) a rebranded Clevo notebook with a Core i5-2410M and no other
video card.
I have a GPU crash dump that I'm attaching here. I will try to boot with
special options listed on
<a href="https://01.org/linuxgraphics/documentation/how-report-bugs">https://01.org/linuxgraphics/documentation/how-report-bugs</a>, but I don't know if
I will be able to reproduce this problem reliably.
Once again, if there is anything else that I can provide, please just ask.
Thanks,
Rogério Brito.</pre>
