dmesg on kernel 4.7
I'm getting a GPU lockup on Team Fortress 2 which seems to be related to bug
#80419 since my dmesg is the same as <a href="show_bug.cgi?id=96271#c44">comment #44</a> but this is occurring on Team
Fortress 2 rather than XCOM.
If I run native TF2 with GALLIUM_DDEBUG=800, I cannot reproduce the bug but the
frame rate drops significantly. With GALLIUM_DDEBUG="800 noflush", I was able
to reproduce the hang. This leads me to believe that the issue is related how
high the FPS is running.
My kernel is: Linux localhost.localdomain 4.4.9-300.fc23.x86_64
I've also tried 4.6 and 4.7, all of which hangs.
My ATI driver is: 7.7.99-3.20160524git040a7b8.fc23 (latest commit in git for
radeon)
I've also tried 7.6.1-3.20160215gitd41fccc.fc23 (the latest stable from fedora
23), all of which hangs.
My mesa version is: 11.3.0-0.37.git357495b.fc23
I've also tried 11.1.0-2.20151218.fc23 (the latest stable from fedora 23), all
of which hangs.
I've attached the GALLIUM_DDEBUG output and dmesg. One curious thing is that on
kernel 4.7, the kernel detects a hang and is able to reset the GPU resulting in
a temporary freeze that eventually resumes. However, the freeze will come again
after a short while (and resumes).
As a data point, I don't get any lockups while playing Skyrim on Wine.</pre>
