Just to clarify: you've strapped the Mitsumi for IRQ 5 and configured
the AHA1542B, via the Adaptec BIOS, to use IRA 11. Is this correct? If
the Mitsumi is a PCI card, then it was auto-configured by the BIOS? The
AHA1542B is an ISA card, if I remember correctly, and as such it's
confugured via a setup dip switches on the card and through the Adaptec
"SCSI Select" BIOS utility.

This doesn't make much sense to me. If both cards are
strapped/configured for a particular interrupt, how can it "grab" a
different IRQ? If the Mitsumi is a PCI card, then in your system's BIOS
you should mark IRQ 11 as being "Legacy/ISA" (ie: reserved for the
AHA1542B) so that it won't be allocated to any PCI cards. If they are
both PCI cards, then there's something else wrong, because the interrupt
should only be allocated to one PCI device.
