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
