https://bugzilla.kernel.org/show_bug.cgi?id=75841 Bug ID: 75841 Summary: radeon (radeonsi): GPU crash and resulting kernel problems (hangs etc.) Product: Drivers Version: 2.5 Kernel Version: 3.15-rc3 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: bugspam@xxxxxxxxxxxxxxxxx Regression: No Created attachment 135651 --> https://bugzilla.kernel.org/attachment.cgi?id=135651&action=edit Partial kernel log showing many GPU faults and subsequent page table breakage I'm reliably able to trigger GPU faults and various subsequent problems. The crash doesn't happen immediately, so far as I can tell. One known trigger is to start a map then start another map on Unvanquished (http://www.unvanquished.net/). It appears that the heat haze option needs to be enabled (this one seems most reliable), and I think that the motion blur option may also trigger this. Known effects, other than reams of GPU fault reports, include hard lock-ups and page table corruption; the attached file (gpu-crash-etc.txt) shows the latter (I chose to reboot soon afterwards). Hardware is Bonaire XTX. Userland is X git (2535b76) with corresponding Radeon DDX, Mesa 10.2 git (e05ceba, built using xorg-edgers packaging), llvm 3.4-2 (Debian). GLAMOR is enabled. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
