releng/15.0 started panicing since Oct 24

Hi,

I have aarm64 running on Parallels VM.
I've been following stable/15 and then switched to releng/15.0.

This system started crashing frequently after updating Oct 24, last Friday.
I first saw a crash on Oct 25, last Sat day.
I wasn't sure if it was my own problem or other factors.
I fully rebuilt again from source but crash didn't go away.

The crash seems to have right after resuming from a suspend.
Crash doesn't happen on every resume, though.
I don't think I know the reproducable procedures, yet.
