Bug ID: 99194 Summary: Certain games cause GPU resets Product: Mesa Version: unspecified Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 Assignee: dri-devel@lists.freedesktop.org Reporter: alex@kobran.org QA Contact: dri-devel@lists.freedesktop.org
Created attachment 128647 --> https://bugs.freedesktop.org/attachment.cgi?id=128647&action=edit 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 loading 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 dmesg starts)
The card in question is:
Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Cayman/Antilles HDMI Audio [Radeon HD 6930/6950/6970/6990]
and as such uses the r600 driver.
Running Gentoo ~AMD64, if it helps.
