           Summary: System locks up when watching fullscreen flash video
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: realnc@gmail.com


(I have no idea if I filled the bug details correctly; I'm simply assuming this
is DRI related. Could be a mesa bug or xf86-video-ati problem, or whatever;
I've no idea.)

There is a regression in kernel 2.6.38 that was not there in 2.6.37: When
switching a flash video to fullscreen, three things can happen:

 * The system locks up completely (not even SysRq works)

 * The screen becomes black but the system is still
   responding (switching to a console and restarting X works)

 * The screen stops updating (old windows are still there even
   after closing them.)

There's no dmesg nor any X.org.0 output when any of the above happen.

I'm running Gentoo AMD64, kernel 2.6.38.1, x11-drivers/xf86-video-ati Git
master, mesa Git master, xorg-server 1.9.5.  My graphics card is a Radeon
HD4870.  I'm using KMS and Gallium and I'm on KDE 4.6.1 with desktop effects
enabled.
