Hello,
I don't think this is a BIOS issue, but a kernel bug in the i386
tree. I believe this was recently discussed and hopefully fixed by
Andi Kleen in the kernel mailing list:
http://lkml.org/lkml/2006/1/9/442
My symptoms are identical, so it's probably that bug. I guess my bug
report through FSC's official support channel will bounce eventually
then ;)
This is a critical bug especially for systems running AMD Dual-Core
Processors on i386 kernel configuration w/ powernow-k8.
The reason for "powernow-k8 - out of sync" errors is because the
cpufreq driver is not aware [or has the wrong idea] about which CPUs
are tied together, because cpu_core_id and phy_proc_id data is
wrong.
Now this is fairly harmless as Mark mentioned, but only on single
socket Dual Core systems.
It doesn't crash my machine, but it also doesn't seem capable to
really lower the clock frequency...
I was wondering if anyone has already tested Andi's patch, if it
successfully solves this problem, and if the patch has made it into
the git yet.
I can give the patch a try if you feel that would help, albeit I
prefer not rebooting my workstation ;)
