          Priority: medium
            Bug ID: 58667
          Assignee: dri-devel at lists.freedesktop.org
           Summary: Random crashes on CAYMAN
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: v10lator at myway.de
          Hardware: Other
            Status: NEW
           Version: DRI CVS
         Component: DRM/Radeon
           Product: DRI

This is with newest mesa from git with kernel 3.8-rc1 (+ this patch:
http://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-fixes-3.8&id=668bbc81baf0f34df832d8aca5c7d5e19a493c68
)

The screen first freezes (mouse still movable, keyboard not responding, not
even to MagSysRQ), then the monitor goes off (standby) and back on with only
garbage on the screen. 

Not sure if this has anything to do with it (but it should get fixed anyway)
but dmesg gets spammed with this:
[  533.928472] radeon 0000:03:00.0: GPU fault detected: 146 0x00335514
[  533.928477] radeon 0000:03:00.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR  
0x00000000
[  533.928483] radeon 0000:03:00.0:   VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x00000000

where the address isn't always the same, example:
[  533.928374] radeon 0000:03:00.0: GPU fault detected: 146 0x0033ed14
[  533.928379] radeon 0000:03:00.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR  
0x00000000
[  533.928385] radeon 0000:03:00.0:   VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x00000000
