I had exactly this problem on my IBM T30 (1.8 GHz P4). Random panics,
usually 4 or 12. Not repeatable.Oddly, many (most?) of the failures were
not during compiles, but doing rm or chmod or something similarly
trivial!  Very weird.

After trying for a while to get a clean build, I finally started
re-starting the buildworld with -DNOCLEAN (occasionally after deleting
something that was in progress) during the build.

Once I got a new system build, things were fine again. I immediately
rebuilt again, as it was possible that something had been messed up in
one of the panics and I missed it.

I could also not update some ports.

I have no idea of the cause, but I have not seen it again.
