mmm in normal operation, can the system run severall hours without pb?
(in case of over heating (fan hs), system quartz failure, ...)

And when system hung, if you wait some minutes (about 3 min iirc), don't you read SCSI BUS RESET messages at the console?

That said, it would make me thought to a pb I encounter with my c110 (exactely the same decription) but the driver pb was 
ncr53c720 (not concerned here) and for some 2.6 only (no pb with 2.4)

mmm I just noticed:
...
Cujo version 2.0 found at 0xf1000000
Enabling Cujo 2.0 bug workaround
Don't recognise Cujo at address 0xf1000000, not enabling workaround
Cujo: No PCI devices enabled.
...

duno if it's important or not?

Iirc it should stand on "hpux Support+" cd

Trust me this logic has no sence in electronic: 3 weeks ago we (I mean an Hp engineer) power off a N system to add a FC card, when 
we try to restart, ...
too bad the boot disk was definitively HS (even thought we check it carefully with mstm before shutdown: the disk never presents 
any pb before?)

That said, the final step is to 'TOC' your system when it hung (do you know the bleue button behind your box?)
then grab the 'ser piminfo' and analyse what you grab on your system when it reboot with
