trouble with K8T Master2-FAR (dual Opteron)

[Satoshi Sato]

Hello,

I'm trying to install FreeBSD/amd64 to dual Opteron machine.

  M/B: MSI K8T Master2-FAR
  CPU: AMD Opteron 240 x 2
  Mem: 512MB x 2 ( in Slot 1 and 3, Single channel)

I had some trouble with this installation.

I couldn't boot FreeBSD normally. Even from CD-ROM.

1. dual CPU : Normal boot

    HUNG UP after memory check(?).

    (dmesg)
    real memory  = 1072627712 (1022MB)
    avail memory = 1009385472 (962MB)
    <then, HUNG>
      Messages flow very fast! Looks like broken...
      So, I couldn't read all.

      But It's something like this

      Fatal trap 12: page fault while in kernel mode
      cpuid = 0; apic id = 00
      fault virtual address    = 0x6c
      fault code               = supervisor read, page not present
        :

2. dual CPU : Safe Mode / disable ACPI

    Trouble 1. did not occur.
    But, after mounting root(/) filesystem, it HUNGs.


So.... I removed one CPU, and installed FreeBSD/amd64. Succeeded!
And I re-compile kernel without SMP option.

Now, this dual Opteron machine boot normally. But vainly.

Does anyone have any idea?
If this is known bug, what can I do for ethis.

I'll appreciate any help.

Sincerely
