Powernow-K8 acpi_pss objects error

Postby w6kkt on Wed Jul 01, 2009 6:54 pm

Using DFI LP UT-NF4-Ultra-D, Opteron 170, 2gigs ram & ATI-800pro graphics. Ubuntu 9.08-amd64, Mint 7 & Mint 7-amd64 after hd installation these distro's take way too long to boot, due to "Powernow-K8 acpi_pss objects error" and then attempts to boot from my swap partition (without success) then it resorts to "normal boot". Evidently, something in the kernel is causing this. I just installed the new PCLinuxOS 2009.2 . It boots fast with no errors. On my latest build ( see my signature) Mint 7 and Ubuntu 9.08-amd64 works great with no boot errors. Evidently the older DFI board bios (using latest bios "406) is not compatible with 9.08 kernel.

I found this in my opinion somewhat strange note in a bug report
I saw the _PSS error until I enabled the "AMD Cool'n'Quiet Function" in the BIOS. While the printed manual isn't helpful, the built-in BIOS help specifically says that this enables generation of ACPI _PSS objects (and a few others).

And what is Ubuntu 9.08?

Hi Husse, tnx for the information. Ubuntu 9.08-amd64 is one of nine linux partitions I have on my hard drive. Thank you for the heads up on "AMD Cool & Quiet". I checked the DFI bios and there is no option for "cool & quiet", which this board is supposed to support. In checking further and to my surprise, the Opteron 170 does not support cool & quiet! But I do have it overclocked to 3.75 ghz, so all is not lost. The 170 spec sheet says nothing about cool & quiet.
Thanks much for your input.

I'm afraid that was the only useful thing I found - not the only thing though

I made a typo in my reply. The Opteron 170 is over-clocked to 2.75 ghz. Wish I was smart enough to modify kinit not to look for "powernow K8". This error adds about another 15-20 seconds boot time.
