Asus K8V - acpi/cpufreq
Hi,
There's a fix in 2.6.10-rc1 for a misunderstanding which prevents any power management stuff from working on certain AMD64 systems (My Athlon64 system is running 32 bit Debian but is still affected, incidentally).
(http://kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.10-rc1)

[CPUFREQ] Work around AMD64 2nd identical PST errata
AMD recently errata'd the definition of the PSB/PST for recent Athlon 64
and Opteron parts. The errata allows for a second, identical PST for those parts. The
current powernow-k8 driver will not work in PST/PSB mode on those parts because it
requires there be 1 and only 1 PST.

A simple workaround that seems to be sufficient is mentioned here (http://lists.debian.org/debian-amd64/2004/09/msg00336.html), which ignores the error given when 2 entries instead of 1 are found:
in arch/i386/kernel/cpu/cpufreq/powernow-k8.c comment line 639 out:
return -ENODEV;
Is there a chance of being able to fix this for the kernel in Sarge, or should I wait until after Sarge is released for the 2.6.10 kernel to propagate into Testing?
Regards,
Nick
