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

Previous kernels did not have this problem. The > dsdt is attached. 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 [-- Attachment #2: dsdt.w600 --] [-- Type: application/octet-stream, Size: 15025 bytes --] ^ permalink raw reply [flat|nested] 2+ messages in thread
