             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 at lists.freedesktop.org
        ReportedBy: spamfang1199 at 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:

http://bugs.debian.org/680097 

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.
