Here's an example of a crash on an RPI3 running -current that was
updated the morning of April 8th. The build command was
make -j3 -DWITH_META_MODE > buildworld.log

The panic started with 
 panic: data abort with spinlock held

The crashing kernel reports
FreeBSD 14.0-CURRENT #36 main-n254371-fb8c87b4f3b: Tue Apr  5 22:20:39 PDT 2022

The machine uses a USB mechanical hard drive for root, with 3547 MB of swap.
Only about 10% of swap was in use when it crashed.

The console output, final top window and buildworld log are at
