2.6.12.3/2.6.13-rc3 BUG REPORT - x86_64 with hyperthreading

Hi!
I tried 2.6.12.3/2.6.13-rc3 compiled for x86_64 on Supermicro dual Xeon
with hyperthreading enabled and the kernel gets stuck when trying to
initialize the second CPU.
CPU: Trace cache: 12K uops, L1 D cache: 16K
CPU: L2 cache: 1024K
using mwait in idle threads.
CPU: Physical Processor ID: 0
CPU0: Thermal monitoring enabled (TM1)
Using local APIC timer interrupts.
Detected 12.501 MHz APIC timer.
Booting processor 1/6 rip 6000 rsp ffff81007ff35f58
Initializing CPU#1
CPU: Trace cache: 12K uops, L1 D cache: 16K
CPU: L2 cache: 1024K
CPU: Physical Processor ID: 3
CPU1: Thermal monitoring enabled (TM1)
                  Intel(R) Xeon(TM) CPU 2.80GHz stepping 01
CPU 1: Syncing TSC to CPU 0.
Booting processor 2/1 rip 6000 rsp ffff8100032dff58
Initializing CPU#2

Booting with hyperthreading disabled is OK.
Booting with hyperthreading enabled and maxcpus=1 is also OK.

Here are board/bios details:
Supermicro X6DH8-XG2/X6DHE-XG2 BIOS Rev 1.2a

CPU = 4 - Intel(R) Xeon(TM) CPU 2.80GHz
DRAM Type : DDR2-400
Hyper Threading Technology Enabled

Please advise.

Thanks,

Maxim Kozover.
