Description
This is a regression in 4.20.x, the same userspace works ok on 4.19.
I could bisect, but it's my main machine so I can't quite dedicate the time, any hint would be appreciated.
The kernel is booted using iommu=soft. full iommu hangs on boot, and noimmu disables the wi-fi.
Dmesg:

[ 702.207061] [drm] GPU recovery disabled.
