           Summary: [radeon] Kernel OOPS - NULL pointer dereference in
                    radeon_fence_ref
        QA Contact: xorg-team at lists.x.org
          Severity: critical
    Classification: Unclassified
                OS: Linux (All)
          Reporter: ancoron at chaoslayer.de
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 7.7 (2011)
         Component: Driver/Radeon
           Product: xorg

Hardware:
- GPU: Sapphire Ultimate R7 250 (1002:683f, 1x DVI, 1x HDMI, 1x DisplayPort,
passive)
- Monitor: Dell 3007-WFP HC (30", 2560x1600 @ 60)

Software:
- Ubuntu 14.04
- Kernel 3.13.0-27-generic
- linux-firmware package version 1.127.2


What happened:

After monitor wakeup, I just got back the picture of the desktop (not the usual
locker screen though) but wasn't able to interact with it (no mouse pointer
visible, no screen updates). I then switched to a virtual terminal and back
again, but that didn't help either. I switched one more time and then got this:
