Dear Simon.

Yes, we did. At this moment we have a redundant 300W PSU and it
worked fine.

I think if the PSU causes problems, typical hardware errors or spontanous
reboots might be a indicator, but not the problem of freezing kernel.
In earlier times, when we ordered the TYAN board and its housing, we were
made aware of this problem by some FreeBSD users which had problems with
low power PSU.

Thanks,
Oliver
