Hello,
I've a big problem with my SCSI/PCI setup:

When doing a:
>/sbin/modprobe aic7xxx

Apr 14 09:13:04 test  kernel: SCSI subsystem driver Revision: 1.00
Apr 14 09:13:04 test  kernel: PCI: Found IRQ 11 for device 00:0b.0

Has anyone seen this before?

The problem ONLY appears when I run my PC with a Davicom 100MBPS NIC.
The Davicom runs fine without the 29160!

I already tried shuffeling the boards & IRQs - no luck :-((


Thanks for any tricks or hints,
