I dunno - the machine does this rarely and today seems to be the day on which it likes to produce its long-occurring doesnt-reboot-at-all problem, which is different, and might be a BIOS thing.
Now current mainline is giving me this:
zsh: exec format error: /opt/crosstool/gcc-4.0.2-glibc-2.3.6/x86_64-unknown-linux-gnu/bin/x86_64-unknown-linux-gnu-gcc
and /usr/bin/sum matches that binary on a different machine.
I think I'll go home and knit a sweater or something.
