 Well, that didn't take long. I discovered that the clock battery was dead flat
 and replacing that cleared the "no timer interrupts on CPU 0" problem at least.
 Let's hope that fixes the random resets.

 Here's a stack trace as promised, while running in single-user, I (without
 reflecting on it being possibly a panic trigger) ran fsck without issue but:

# find . > /dev/null
(nothing happens)

# find . > testfil

(long pause)
