I'm trying to boot FreeBSD 6.1-RELEASE/amd64 on an IBM xSeries 336 machine

The installation was successful, but
if I try to boot the SMP kernel, it hangs after detection of SCSI and ATA
devices (possibly when doing the initialization of the mpt0 RAID controller,
or when it tries to start the second CPU?).

Couple questions come to mind: First, will it work if you install i386? Second,
had it ever worked on this system with older releases?
The reason you dont see the second cpu without ACPI is that IBM does not
have the legacy MP table stuff set up, they require the ACPI tables to do
MP (this is intentional not an oversight).
FYI, he disabled support for APICs, not ACPI. :) In this case it
sounds like IBM's BIOS doesn't provide correct interrupt routing info
for the NICs.
