-CURRENT hangs since at least 2022-04-04

[filis+fbsdcurrent]

Hi,

I'm running -CURRENT on this one desktop box which is a "Ryzen 7 4800U 
with Radeon Graphics", since it didn't work on 13R.
I use Boot environments and on 2022-04-04 I updated it and it started to 
completely freeze under X (I haven't tried letting it run without X) 
after a few dozen minutes.
I went on vacation and came back today and updated it again to see if 
the issue went away, but it froze again. I went back to the latest BE 
before 2022-04-04, which is from 2022-03-21 and so far it works fine 
again. I use a different machine to build and then rsync /usr/src and 
/usr/obj over and run make installworld, etc locally and also pkg 
upgrade (I use FreeBSD -latest packages) everything, so I can't quite 
tell if this is related to base or drm-kmod and I'm not too familiar 
with changes in the timeframe between 2022-03-21 and 2022-04-04 that 
would affect my setup.
Is there anything I can try and/or find or collect info to shed more 
light on this?

Cheers,

filis
