Problems with emu10k1 on SMP machine

Problems with emu10k1 on SMP machine

[Eugene Kuznetsov]

Hello everyone,

      here's a little problem I'm experiencing ... I am trying to set
up Linux ( kernel 2.4.18 ) on SMP machine ( 2 AMD Athlons XP, AMD 762
motherboard ). First of all, it wouldn't even boot up unless I turned
off either MPS 1.4 ( in BIOS ) or APIC ( in kernel ). Without one of
them, it boots, but now I have another problem. I can't make emu10k1
based sound card to work. I receive this:

Creative EMU10K1 PCI Audio Driver, version 0.18, 08:34:52 Apr 16 2002
PCI: Enabling device 00:09.0 (0004 -> 0005)
PCI: No IRQ known for interrupt pin A of device 00:09.0. Please try using pci=biosirq.
emu10k1: IRQ in use

If I try to insmod emu10k1.o with 'pci=whatever' parameter, insmod
complains about not having 'pci' module parameter.

I tried turning on and off MPS 1.4, APIC, even completely disabling
SMP in kernel. Nothing helps. Sometimes error message contains
mentions of 'buggy MP table' ( why would it be buggy - everything
works perfectly in Windows? )

Is there a way to fix it?

Your system hasn't allocated the Emu10K an interrupt and it cannot find an
interrupt for it. We don't have AMD762 IRQ router support in 2.4.18 at the
moment although I believe we have the needed documentation.

I think so.. care to be the test pilot ?
