Hi,
I'm running Gentoo Linux on an Athlon 64 system (board is Asus 8KV SE
Deluxe). I was getting the "BIOS error - no PSB" message when trying to
"modprobe powernow-k8", so I upgraded to 2.6.5-rc3-mm4 which includes
Pavel Machek's new powernow-k8 driver. Theoretically, it should be
getting tables through ACPI and ignore the legacy PST/PSB tables, but
I'm still getting the same error as before and inserting powernow-k8
fails with this message:
FATAL: Error inserting powernow_k8
(/lib/modules/2.6.5-rc3-mm4/kernel/arch/x86_64/cpufreq/powernow-k8.ko):
No such device
Is there anything I need to tell the kernel explicitly to inform it not
to use the legacy method? Any kernel options I might have overlooked?
BIOS support for ACPI 2.0 is activated and APIC APIC Supprt enabled. I'm
confused about this boot message, though:
PCI bridge 00:01 from 1106 found. Setting "noapic". Overwrite with
"apic"

Try putting it directly into kernel.

When do you have a heart between your knees?

You have ACPI disabled right?
If yes this patch will fix it.
But you should enable it, otherwise the powernow driver works just like
the old one.

No, I have it enabled. Another AMD64 user sent me his kernel .config which
I tried, and it worked. Then I slowly went back to my original kernel
.config step by step to find out what the culprit was. I was amazed to
find out that powernow-k8 still worked after I had gone back to my
original .config (took me half a day and about 50 reboots). Impossible for
me to say what triggered this change of mind of my system, but it works
perfectly now without me changing anything.
Sometimes I feel that even in the digital world there are things beyond
explanation ;-)
