           Summary: Oops associated with radeon_unpin_work_func
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.38.2
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: smf.linux@ntlworld.com
        Regression: No


If this system (LFS build) is left idle for several hours with xscreensaver
running(don't currently know which screen saver app. I am assuming one of the
Mesa 3D ones) the system will oops. The system is locked solid and there is no
trace in messages.old on reboot. The attached jpg is a photo of the screen at
system failure. I first noticed the problem in 2.6.38-rc8 but have waited until
now to report the problem in the hope of obtaining a more repeatable scenario.
