MSI K9A2 Platinum Rev.1 bios update from 1.1 to 1.5 breaks ACPI _PSS objects

[Benjamin Scherrer]

Hi,

I just updated my bios on the MSI K9A2 Platinum mainboard from version 1.1 to 1.5. Unfortunately, cpufreq is not working any more, and "modprobe powernow-k8" gives me:

"powernow-k8: Found 1 AMD Phenom(tm) 9850 Quad-Core Processor processors (4 cpu cores) (version 2.20.00)
powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands. Please report this to the Linux ACPI maintainers and complain to your BIOS vendor."

I complaint to MSI, and am kindly asking you for advice what to do now, since I don't want to run all my cpus on 100% all the time. Will the cpufreq_ondemand governer also work without the PSS objects?

greetings,
Benjamin

p.s. I mailed MSI that they should contact you at http://www.lesswatts.org/projects/acpi/ (just as info for you, they most probably won't do anything I guess)

Hi,

wow, MSI replied very fast  - they sent me an e-mail with a link to the
new 1.6.5 bios (dated early this month, it's not officially out yet).
Cpufreq is working again.

Thank you for the good powernow-k8 output; it got me to the solution in
less than a day!

Benjamin
