core.text from crash

I have had multiple crashes on a new Alder Lake system (Lenovo T16 (Intel)).
The backtraces on all showed vfs and a couple also included softupdate.
Softupdate is further implicated by the fact that "fsck -l /" consistently
reported "SOFTUPDATE INCONSISTENCY" and required a full fsck and managed to
corrupt the pkg database at least three times. In all cases, I was building
ports on the system.

Due to this being a fresh install, I was unable to get a dump, but I finally
got one this morning. I disabled softupdate and have yet to have a crash; yet
another indication that softupdate is the trigger. Possibly a race caused by
the different speeds and thread counts of the different cores.

FreeBSD 14.0-CURRENT #0 main-n257619-c1a0ab5ec52: Fri Aug 26 09:37:24 UTC 2022

I will attach the core.text file to this report.
