Summary: page faults / general protection faults under heavy 3d load Product: Drivers Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: niels_ole@salscheider-online.de Regression: No

I get page faults or general protection faults under heavy 3d load (like "sauerbraten", but sometimes switching windows with kwin is enough) in random processes. I have a radeon hd 6870 and use r600g from mesa git.

This happens on 3.0-rc1 and 2.6.39. I am not sure if this is a problem with older kernels, too, since I get gpu lockups with them.

I am not sure what could cause these problems, maybe some bug in gem / ttm?

--- Comment #9 from Alan alan@lxorguk.ukuu.org.uk 2012-08-24 16:36:07 --- The page allocation warnings are fine (and just warnings that perhaps the VM needs further tuning)

The only oddity is this

[drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!

--- Comment #10 from Alan alan@lxorguk.ukuu.org.uk --- Which is an out of memory error so correctly just a warning
