dmesg output taken right after the event
Under both 13.0.2 and git versions of mesa, certain games cause complete gpu
lockups which are only sometimes recoverable.
The Non-free (as in beer) game Saints Row IV exhibits this behaviour shortly
into the loading screen. System recovery is only possible within the first =
few
seconds using the Sysreq key. After about five seconds the system fails to
respond and requires a hardware reset.
The Free (again, as in beer) game Unturned exhibits this behaviour upon loa=
ding
up a map (for my purposes I used the PEI map that is the default). System
recovery is typically possible by simply closing the game, but sometimes
requires a VT switch to kill the process.
This behaviour is present both in 13.0.2 and the git version at Dec 16, 2016
16:30:30 MST. This behaviour also appears in at least kernel versions 4.9.0=
and
4.8.14
Dmesg output is provided, albiet oddly truncated (That is exactly where dme=
sg
starts)
The card in question is:
Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cayman/Antilles HDMI A=
udio
[Radeon HD 6930/6950/6970/6990]
and as such uses the r600 driver.
Running Gentoo ~AMD64, if it helps.
