Sure! Thanks IIlia!

The patch did not apply cleanly on top of 13.0.3 nor master though (in
src/gallium/drivers/nouveau/nvc0/nvc0_query_hw.c line 406 [1]) so I changed
"nouveau_pushbuf_space(push, 16, 2, 0);" to "nouveau_pushbuf_space(push, 32, 3,
0);" to match the content of your patch, I hope this is right (sorry, I'm not
familiar with this code).

But the issue is quite random and rather hard to reproduce at will, so I'll run
with this for some time see if the issue reoccurs.

I shall also prepare a test package for Fedora downstream with the (modified)
patch included so that the original reporter can give it a try as well.
