Comment # 4 on bug 965505 from Egbert Eich

I said I know when above condition arises I did not say I know the cause. It
arises when the GPU is busy for a longer period of time while the user is
moving the mouse. Now this can happen because the GPU is wedged or just busy.

The report was free of any context:
1. There is no description of the observed behaviour when this happened:
   - Did the GPU wedge for good or did it come back again?
   - If the latter, did this reoccur?
   - Any observations what was happening when it occurred?
2. There is no way for me to try and reproduce the problem as it doesn't even 
   mention what video (?) application was used and under which circumstances -
   was there a certain setting that triggered the issue?
3. There were no logs - no Xerver log file, no output of 'dmesg'. 

Most of this is straight forward - and since the backtrace from the log was
published the log file itself was known.
I'm really getting tired getting picemeal reports having to extort every little
piece of information myself.

There's a backtrace in the log: This is valuable in narrowing down the cause
only when I have the exact version of the modules listed there:
/usr/bin/X
(/usr/lib64/xorg/modules/input/evdev_drv.so)
/usr/lib64/dri/radeonsi_dri.so
(/usr/lib64/xorg/modules/libglamoregl.so)
This is not immediately obvious therefore I would have asked for id if a bit
more context had been available at least.
