I'm having problems with IRQ allocation. It seems that every device is
being allocated with IRQ 9 including both of my PCMCIA slots and
video/sound/modem/firewire/usb. The BIOS seems to incorrectly map both
my PCMCIA slots to IRQ 255 which Linux then remaps to IRQ 9.
I run into problems because my sound card won't work properly when on
the same IRQ as my CardBus ethernet controller. PNP has been disabled in
my BIOS and I've tried switching the PCI scanning to both BIOS and
Direct without any change.
I'm running a Sony Vaio PCG-XG9 laptop with 2.3.99-pre4-2. Serial ports,
IRDA, and parallel ports have been disabled in BIOS in a hope to free
some IRQs.
Below I've included a scan of /proc/interrupts, lspci -vxx as well as my
bootup with full PCI debugging turned on.
