It's probably the infamous "tstiling".

Next time it hangs you can break into DDB from console and check with
ps (ddb command, not ordinary command; see ddb(4)).  I've seen such
lockup once on my newly installed mini g4 when I was copying over
several cvs trees from the old machine.

Cc'ing tech-kern@ may be of help, it's probably MI problem, not
specific to macppc.
