Another? drm panic not involving Radeon and probably not wifi

This may be tied to a thread that seems to have ended on Jun  3 but I'm
unsure.

I had updated my system to main-n277763-2542189532b3: Fri Jun  6 14:11:24
PST. Builds and installs went fine, but the system panics when DRM starts.
I don't get a dump.My prior kernel,
main-n277560-99976934274d: Thu May 29 12:13:12 PDT seems to work fine.
Running with the new world, but so far, so good.

Is this the panic in the June 3 thread?
System is Alder Lake with 12 threads. Did have to rebuild vbox modules to
get back to working on the 99976934 kernel
Here is the panic:
