My experience is it depends.
My sound card, a SB AudioPCI couldn't share an IRQ with anything with LM 8,
or RH 7.1, though it did under 7.2.
My Advansys SCSI card, which shared an IRQ with USB and something else under
7.2 gave me problems, as did my Adaptec 2940 card. And my second Linksys
card gave me problems.
OTOH, I just realized that I'm sharing an IRQ again with my sound card, and
it is working. Apparently, when I reset the BIOS after a recent flash to
support a large hard drive, it changed. And is working, though I have been
getting APIC errors and have been having heat problems.
I think it may depend on just WHAT is sharing the irqs.
For instance, I am currently running with the following configuration:
CPU0 CPU1
0: 1240367 1273317 IO-APIC-edge timer
1: 888 889 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
9: 38734 38768 IO-APIC-level eth0, es1371
10: 6506 6961 IO-APIC-level usb-uhci, eth1
11: 377 311 IO-APIC-level aic7xxx
14: 94704 94832 IO-APIC-edge ide0
15: 1021 769 IO-APIC-edge ide1
NMI: 0 0
LOC: 2513518 2513516

Subject: [expert] Are PCI interrupts allowed to be shared in
8.0/kernel2.4+
Reposting.... Still need to know if shared PCI interrupts are a problem in
the 2.4 kernels.. The 2.2 kernels allowed shared PCI interrupts on my
machine..
