Look, I have a U5 with nothing running except ssh so I can login and do
kernel builds. It has never locked up like this.
Since the only difference between your U5 and mine is that your physical
hardware is not mine (meaning maybe you have memory errors, or cpu/fpu
is too hot and is producing problems) and you are behind a firewire, I'd
go with one of those problems.
