Hi,

if I enable CONFIG_X86_UP_IOAPIC in 2.5.42 with ASUS A7V8X motherboard using VIA KT400 northbridge and VT8235 southbridge, the kernel freezes right after uncompressing without printing anything. Just turning off this option makes it boot correctly. The BIOS has option to use PIC or APIC and is set to APIC. MPS version can not be set.

The same option "works" in 2.4.20-pre10, ie. it doesn't crash, but doesn't use APIC IRQs either.

Is this a known problem? Any ideas on how to debug this?
