I am seeing *exactly* the same hang problems in a machine with an SMC
Ultra in it at the moment.  The problem is that it doesn't seem to
matter too much what kernel is running on it, which makes me suspect
that there might be some hardware problem in the machine.

The machine (polgara.it.com.au) was up for 10 days, and then it just locked
solid.  Hard reset.  10 minutes.  Locked up again.  Reset.  15 minutes.
Lock.  Reset.  10 minutes.  Lock...  etc. for about five more reboots.
I then took the machine apart, checked everything, switched it back on
(with the 1.2.8 kernel with net patches) and it was up for 3 and a half
hours, at which point I decided to reboot with 1.2.8 without the patches
because NFS was hanging on the patched kernel.  Reboot.  15 minutes.
Lock.

I then powered the machine off for 15 minutes, rebooted, and it has
managed to stay up overnight so far, which does make me suspect some
hardware fault.  The power off reboot this time was with a non-net-
patched kernel.

It is most frustrating.
