I'm having a problem installing FreeBSD/amd64 SMP on a
couple of IBM x346 servers. Both have dual XEON 3.0GHz
EM64T processors but OS seems to only enable one of
ACPI has to be disabled on both machines for them to
boot, otherwise they will hang after probing the
I'm using the SMP kernel config unedited.
Mptable on both machines show that there are 2 CPUs:
Processors: APIC ID Version State Family
Model Step Flags
0 0x14 BSP, usable 15
4 1 0x0301
6 0x14 AP, usable 15
4 1 0x0301
Sysctl hw.ncpu returns 1 on both systems.
The one on FreeBSD 5.4 has 6GB or memory and the one
on FreeBSD 6.0 has 3GB of memory. I can run tests on
the 3GB system and will probably try FreeBSD/i386 on
it to see if it can see both CPUs.
Has anyone successfully ran FreeBSD/amd64 SMP on these
Thanks in advance for any info anyone can provide.
