Ok. If you pop the 150MHz card back in is it stable again? If so,
then something on the bus can't handle the faster access time. My first
suspect would be the memory. As an experiment, pull all but the first
bank of memory out (ya, I know it's a pain to do). Also, if you have any
cards plugged into the PCI bus, pull them too, as well as any harddisks
which aren't needed to boot the machine. If that works, swap those
modules with the next set of memory. The objective is to find which
modules are marginal. If all memory passes, try re-inserting the drives,
one by one, followed by the cards.
Good luck.
