can not boot SMP kernel on GA-8EGXDR-E

[Igor Sysoev]

I can not boot SMP kernel on GA-8EGXDR-E motherboard in
Gigabyte GS-SR222E server - it hangs on SCSI disks after CPUs launched:
-------

In maillists I found two the same reports without resolution:

on GA-8EGXDR-HT:
http://freebsd.rambler.ru/bsdmail/freebsd-smp_2003/msg00452.html
on GA-8EDXDR-HT:
http://freebsd.rambler.ru/bsdmail/freebsd-smp_2003/msg00587.html

I had tried 4.8-RELEASE, 4.9-RELEASE and 5.1-RELEASE SMP kernels
with and without HTT. All of them are hangs in the same place.
4.8-RELEASE UP kernel runs without any problems.

The motherboard has three PCI buses on-board:

pcib0   ata0
        ata1
        fxp0
        ...

pcib1   ahd0
        ahd1

pcib2   em0

I thought that there can be some problem with interrupt routing
and IOAPIC so I disabled ahd in kernel config and add IDE disk.
After reboot FreeBSD saw ata disk. This disk has no filesystem
so I can not say just now if SMP kernel can work on this motherboard
with ata and fxp and without ahd and em0.
But it seems that pci0 interrupts works fine.

I can post dmesg of boot -v, outputs of mptable and pconf,
or can try suggested patches and debug sessions.
