------- Comment #12 from [EMAIL PROTECTED]  2008-01-02 13:33 -------
I like your theory that this is caused by a broken BIOS.  However, I would like
to try to work around the problem in the kernel rather than just rejecting the
bug report.

I'm not sure we can tell yet whether
  a) the LNKC device reports "3 4 6 7 10 11 12" as possible IRQs but is in fact
hardwired to IRQ 5, or
  b) 0000:00:10.4[C] is connected directly to IRQ 5 rather than to LNKC.

The kernel thinks Paul's gameport device (0000:00:0c.0[A]) is also connected to
LNKC.  If /proc/interrupts shows gameport interrupts on IRQ 11, then I think
it's more likely that (b) is the problem.

Either way, I think it's possible to work around this.  Paul, can you boot with
no options and try out the gameport to see where its interrupts are going? 
Please also attach the dmidecode output, so if we write a workaround, we can
make it specific to this motherboard.
