[LinuxBIOS] Tyan S2885 interrupt problem...

[Richard Wei]

Traped in the interrupt problem for a long time. Need someone's guidance.

When I disabled SMP and Power Management support in Linux 2.6.14, 
I was able to enter the shell without any IRQ ability (IRQ=0) for all PCI devices.

Checking for some discussions and found out that most of the successful case
has to turn them on, and expect I/O APIC and local APIC to assigned IRQ for
PCI devices. Am I on the right track? Or is there other method to assigned IRQ?

But everytime init_lapic_sysfs called, the kernel hang~ Did I miss anything?
Any suggestion is appreciated~
