------- Comment #9 from [EMAIL PROTECTED] 2007-12-17 21:40 -------
Thanks for the info.
The problem in this bug is caused by the following error in SSDT:
CreateDWordField (Arg3, 0x00, S*S0) //S*S0 can't be recognized by ACPI
interpreter and it is very clear BIOS bug.
Because of this error the _PDC method for CPU0 can't be executed so that OS
can't load table dynamically from the address of 0x7fed0735 and 0x7fed0412 ,
which contains the CST and PSS for CPU0. But the CST and PSS for CPU0 is
refered by CPU1, so OS will report the error message of AE_NOT_FOUND(CST, PSS)
and acpi_cpufreq driver can't be loaded correctly.
This is a BIOS bug and can be fixed by BISO update.
