Description:
I just switched my main GPU from dedicated Radeon to integrated Intel because of VGA passthrough (so host=arch uses the integrated one now). Since this change my X server crashed multiple times with the following backtrace:

[ 1591.324] (EE) Backtrace:

It duplicates  FS#66818  I think - backtrace is exactly the same. Also crashes happened on mesa 20.1.0-3 still and do not happen since the update to -4.

It was kinda late, sorry for noise.
