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.
