Every MB's mptable.c is different.

I think the I/O APICs are incorrectly assigned to buses. From the kernel
messages, devices on bus 0 are transformed to high IRQs.

Can anyone one confirm that the mptable.c under src/tyan/s2735 is a good
one to boot SMP linux kernel? I might need to manually construct the MP
table for my board according to a good one.

Thanks,
gin

problem with booting SMP linux kernel

[Gin]

I've adjusted my MP table to use the correct IRQs. But the IDE interrupt
is still lost. There is some message from linux kernel that I didn't
understand. Is there something wrong with my timer settings?

================================================================
..MP-BIOS bug: 8254 timer not connected to IO-APIC
...trying to set up timer (IRQ0) through the 8259A ... 
..... (found pin 0) ... failed.
...trying to set up timer as Virtual Wire IRQ... works. 
===============================================================

This is the last line where the kernel stops.
=================================================================
hda:<4>hda: dma_timer_expiry: dma status == 0x24
=================================================================

Does anyone have an idea?
