I've gotten a couple of people that have responded with somewhat
different advice. One thought it was likely to be a problem with the
PCI bridge chip, the other with SMP.
I have switched to a non-SMP kernel (otherwise identical to what
I was previously running), I have tried moving both of the 2940U2W
controllers to either the primary or secondary PCI busses (on the
primary, one of them shared IRQs with the AIC-7890 controller, but on
the secondary although they share the PCI bus with the AIC-7890
controller they all at least have different IRQs and I/O Base
Addresses). So far, nothing has worked.
I can't do it tonight, but maybe tomorrow sometime I can dig up
one of those bloody Pentium III terminator cards and actually
physically remove one of the CPUs to see if that makes a difference.
Anyway, here's the latest dmesg output (with all three SCSI
controllers on the secondary PCI bus):
