Summary: Radeon HD 5750: GPU lockup CP stall while browsing in Firefox Product: Drivers Version: 2.5 Kernel Version: 3.0-rc5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: jlp.bugs@gmail.com Regression: No
I was browsing with Firefox 5.0 (in KDE 4.6.4 with desktop effects enabled) and when I clicked on a button to return to the previous page the screen suddenly all got black and when it came back the mouse pointer was not visible but the windows under it reacted to mouse-over. I had to switch to bob-X virtual console and then back to restore everything. Well I also immediately checked dmesg and this is what was in there:
