>Description:
Nothing special; just happened. Booted my laptop as normal and hit the
panic right about when xenodm is about to start or right after it. It
happened quick enough that I didn't manage to see if it started or not.
The important part is that it happened after the system fully booted,
and in particular after the filesystems were mounted.
I have the pictures so I can provide the functions arguments on demand.
