https://bugzilla.kernel.org/show_bug.cgi?id=31712 Summary: GPU lockup CP stall after resume from hibernation Product: Drivers Version: 2.5 Kernel Version: 2.6.38 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx ReportedBy: psusi@xxxxxxxxxx Regression: No When resuming from hibernation on my Asus P8P67 Pro Core-i5 2500K system with a Radeon 4850, I get a GPU lockup CP stall error, which leaves the display in a corrupt state. The kernel attempts to reset the display to no avail, landing back in the lockup again and again. A sysrq-K to kill X.org resolves the issue. The issue seems to be tied to plymouth. If I boot without the quiet and splash options when resuming, it resumes just fine. Suspend also works fine. This occurs with the stock Ubuntu Maverick 2.6.35 based kernel, the Natty 2.6.38 based kernel, and the Linus 2.6.38 kernel ( last two built from source ).
