today I migrated my computing environment from a Asus P5A K6 to a dual
celeron an a Abit BP6. I unplugged the cards in one chassis and
transferred them to the new one and finally got everything booting and
running with the old (2.2.13pre10) uniprocessor compiled kernel. Then
I fetched 2.2.13 and patched it to pre5 with SMP enabled, but no
networking option changed.
With the uniprocessor kernel, my (quite old, 1997 vintage)
3c905 PCI card was recognized at IRQ9:
Nov 15 17:21:36 hertz kernel: 3c59x.c:v0.99H 11/17/98 Donald Becker \

0xa400, 00:60:97:11:c0:98, IRQ 9
The SMP kernel had trouble with that card:

Going back to the UP kernel made the problems go away again, but even
v0.99L didn't help in the SMP case.
So I decided to move the card to some other PCI slot where it got
another IRQ
hertz kernel: eth1: 3Com 3c905 Boomerang 100baseTx at 0xa400, 00:60:97:11:c0:98, IRQ 11
hertz kernel: 8K word-wide RAM 3:5 Rx:Tx split, MII interface.
hertz kernel: MII transceiver found at address 24, status 782f.

where it worked again.
/proc/interrupts doesn't show anything else on IRQ9:

Has anybody an idea why it didn't work with IRQ9?
