Could be heat or flakey RAM.

Someelse reported this as well and I've filed a bug on it at API.

So far we've been unable to reproduce it, but we'll run through it again.

2 are firmware setup, 2 are cache size (which is fixed). I don't think the
other 4 are used.

There's no halt connector on the motherboard, so no.

Get 2.2.16 (or later), get the patch from the API website:
http://www.alpha-processor.com/products/downloads/customer_support/UP1100/
trident-2.2.16.patch.bz2
build the kernel as either Nautilus or Generic, say yes to trident sound
card support.
