Swapped cpu's AMD 3000 to AMD 4000- now getting ACPI exception error

[agerardi]

Swapped cpu's AMD 3000 to AMD 4000, now getting ACPI exception error.

Excerpt: ACPI: Processor [CPU0] (supports 8 throttling states)
ACPI Exception (processor_perflib-0234): AE_NOT_FOUND, Evaluating _PSS [20070126]
powernow-k8: BIOS error - no PSB or ACPI _PSS objects

So now powernow K-8 throtting does not work. Do you think I may need to recompile my kernel for different cpu chip?

Appreciate any assistance.

I would. The architecture is most likely different on the 3000 to the 4000

I agree. Whenever you install new Hardware on any version of an OS you need to make sure the firmware/drivers are installed because no two parts are exactly the same even if they are only one model number away.

Well I didn't recompile my kernel. I updated the bios.....and that worked. Recompiling the kernel was going to be my next option.......
Tks for all the advice.

Not bad. So all you had to do was update your BIOS?

Yep. That did it.
