I just installed FreeBSD 15 on the RPI 3b+ using the official image. Everything
works great, except the shutdown process. On the final shutdown stage, it's
crashing on muge0 with a panic. Similar behavior was also observed by another
user:

I also found that if I physically unplug the cable, a crash does not occur, so
my expectation is that there is some race in the shutdown process.
