Which one is yours:

?

Also, can you send /proc/cpuinfo pls.

Hmm, can you enable all the debug statements in the driver?

Simply edit drivers/cpufreq/powernow-k8.c by adding

#define DEBUG

as the very first line in the .c file.

Then rebuild kernel, reinstall and reboot with "ignore_loglevel
log_buf_len=10M" on the kernel command line.

You can send me dmesg privately if you prefer.

Thanks.
