Description
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 e73f88af66fcc50083fae4b7e1c39b469179a97agit20110215.cc1636b6-0
DRM/mesa/etc:
ii libdrm-radeon1 2.4.23-1ubuntu3
ii libdrm2 2.4.23-1ubuntu3
ii libgl1-mesa-dri 7.10.1
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
