Joe,
I had a similar problem after installing an AHA1515 SCSI card. In my case it was
an interrupt conflict with a PCI USB controller. This was not immediately obvious
as 'cat /proc/interrupts' doesn't report PCI devices:
0: 8380778 timer
1: 4125 keyboard
2: 0 cascade
4: 2153 + serial
5: 1197 3c509
10: 13365 + BusLogic BT-958
<----<<< Huh?
12: 186 + aha152x
13: 1 math error
14: 24898 + ide0
15: 473 + ide1
But my (Slackware) system also has /proc/pci. I 'cat' this and got:
Bus 0, device 7, function 3:
Bridge: Intel 82371AB PIIX4 ACPI (rev 1).
Medium devsel. Fast back-to-back capable.
Bus 0, device 7, function 2:
USB Controller: Intel 82371AB PIIX4 USB (rev 1).
Medium devsel. Fast back-to-back capable. IRQ 11. Master Capable. Latency=32.
I/O at 0x6300. ^^^^^^^
So have a further look for interrupt conflicts. The adaptor is sure not happy on 11:
