           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 at kernel-bugs.osdl.org
        ReportedBy: psusi at cfl.rr.com
        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 ). The
kernel log shows:
