Comment # 1 on bug 81907 from 
Some information in case someone tries to reproduce it.

I applied this patch additionally to the revert:
https://bugs.freedesktop.org/show_bug.cgi?id=80880#c10

Many demos work now. But the Cave Demo does not work, it hangs the GPU.

I can not reproduce the original bug I posted here anymore with the patch, just
the hang. It looks like this:

ring 0 stalled for more than 10146msec
GPU lockup (waiting for 0x000000000000a921 last fence id 0x000000000000a920 on
ring 0)

GPU reset succeeded, trying to resume


I'll leave this bug report open, because I have no idea if this bug will
reappear once the hang is fixed.
