Bug #: 55006 Summary: video playback causes total freeze on RV350 Classification: Unclassified Product: DRI Version: XOrg CVS Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: spamfang1199@yahoo.de
Video playback and switching between tabs while browsing often leads to total freeze of my system. Even the magic SysRQ keys wont work then.
steps to reproduce: Watching movies with vlc, or switching between tabs is often enough to freeze the system.
It all started with introducing KernelModeSetting to Linux. This bug has been affecting me since i upgraded from Debian Lenny to Squeeze and thus to Kernel 2.6.32. I could avoid that bug however by adding "radeon.modeset=0" at the boot prompt from 2.6.32.
Now with Linux 3.2 even passing "radeon.modeset=0" at the boot prompt does not work any more for me.
I reported the bug to Debian and they told me to try Linux 3.5, which also freezes often. For reference here is the link to my bug report:
This is a very serious regression for my RV350 and causes file system corruption & data loss (for my work progress)
I cannot add a log from the freeze, since nothing gets logged then. If you know a way i could give you one, let me know.
