https://bugs.freedesktop.org/show_bug.cgi?id=35045 Summary: BUG at ttm_bo.c:272! (ttm_bo_ref_bug -> ttm_bo_list_ref_sub+0x28/0x30) Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: freedesktop@xxxxxxxxxxx Hi, I've got a repeatable oops that happens when viewing full screen video in flash in chromium, under kwin (with effects enabled) and switching virtual desktop/workspace on ATI Technologies Inc RV710 [Radeon HD 4350]. Hardware: ATI Technologies Inc RV710 [Radeon HD 4350] in an ASRock P55M Pro motherboard, with an i7-860 CPU, and 8GB RAM, connected to Dell S2409W display via DVI. OS: Ubuntu Natty upto date as of today, 64bit install, running KDE. Kernel: Daily build from DRM next from http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/current/ linux-image-2.6.38-996-generic_2.6.38-996.201103041138_amd64.deb claims to be commit e73f88af66fcc50083fae4b7e1c39b469179a97a DRM/mesa/etc: ii libdrm-radeon1 2.4.23-1ubuntu3 ii libdrm2 2.4.23-1ubuntu3 ii libgl1-mesa-dri 7.10.1~git20110215.cc1636b6-0 I've got a 3x3 virtual desktop setup, and am running Chromium and go to youtube and pop a video full screen; and move around the virtual desktop with ctrl-alt-arrows. The oops below was produced twice. I've got a bunch of related symptoms; I installed the daily build because I was getting instances of [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -35! (which I think is EDEADLOCK) doing similar combinations of going in and out of full screen flash. I've also seen when I try to go into full screen rapid flickering as if it can't decide whether to go into full screen or stay out; once that's triggered that flickering can repeat itself when starting other apps. This corresponds to Ubuntu bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/717870 and possibly also ubuntu bug 717889 Mar 5 22:12:17 major kernel: [ 495.890854] ------------[ cut here ]------------ Mar 5 22:12:17 major kernel: [ 495.890882] kernel BUG at /home/kernel-ppa/COD/linux/drivers/gpu/drm/ttm/ttm_bo.c:272!
