Hmmm...
it's actually not quite that simple. The card on it's own doesn't cause any
problems. It's when the NMI watchdog stuff is enabled that all hell breaks
loose at least on my 8500R. Basically, every CPU in the system gets hammered
with NMIs (1000's per second). The system is slower than it sh
Ok, on a suggestion from JP, I've built the 2.4.0 kernel without SMP
support. I did, however, have to make one change to a header file to get
it to compile the kernel and here is a diff

This is hardware behaving as designed but not supported by the kernel. IBM was

typically within an hour of booting. The problem was identified as a Wiseman
Systems Management adapter generated hardware interrupt that 2.4 doesn't handle
(this was not a problem with 2.2.x).
