Just some shot in the dark: A few years back I had a similar problem
with a U10 and a Promise IDE card - (apparently) fine without the card
and panics with the card. After a lot of searching and head scratching I
finally swapped the memory around - and one of the memory modules proved
to be faulty. For some odd reason, the machine would only hit that fault
when the Promise card was present. You problem could be similar - have
you tried swapping RAM between the U5 you have, just in case?
Cheerio,
Thomas
