Well, I'm not really using PCMCIA much, but it appears that pretty much
everything else *is* using interrupt 11.
Here's what cs4281.o says when it's loaded:
PCI: Found IRQ 11 for device 00:0b.0
PCI: The same IRQ used for device 00:08.0
PCI: The same IRQ used for device 01:00.0
... and here's my /proc/interrupts:
0: 65911 XT-PIC timer
1: 1151 XT-PIC keyboard
2: 0 XT-PIC cascade
11: 2203 XT-PIC Ricoh Co Ltd RL5c476 II, Ricoh Co Ltd
RL5c476 II (#2), usb-uhci, eth0, Crystal CS4281
12: 718 XT-PIC PS/2 Mouse
14: 670523 XT-PIC ide0
... so maybe things would work better if cs4281.o wasn't using interrupt
Then again, I'm not explicitly allocating any of these interrupts... I
assume the kernel knows what it's doing? ;-)
I tried loading module cs4281 with a different irq, but it refused.
Glancing at the source, there are no MODULE_PARM() definitions, which
leads me to believe that it takes no parameters?
Module 3c59x also refuses an irq parameter to modprobe... so I'm running
low on ideas.
Maybe someone more knowledgeable than I (that's most everyone) has a
