HT: CPU0 detected two times

Hi!

Kernels starting with 2.6.13 detect a HyperThreading CPU two times as CPU0:
ACPI: CPU0 (power states: C1[C1])
ACPI: CPU0 (power states: C1[C1])

Then, the kernel hangs. Previous kernels did not have this problem. The dsdt 
is attached.

regards,
Jörg

The problem exist on various Fujitsu-Siemens computers (W600 series). Kernels 
up to 2.6.12 can boot without ACPI related problems. All tested  newer 
kernels (2.6.13, 2.6.13.3 and 2.6.14-rc3) hang after ACPI cpu detection. I 
attached the /proc/acpi/dsdt output to this mail. What can I do to resolve 
this issue? I solved this problem temporaly by disabling hypter threading in 
BIOS, but there should be a better solution...

regards,
Jörg
