This might be what I've been seeing on my 32 bit install on my Athlon64 system. Below are extracts from some emails I've exchanged with [EMAIL PROTECTED] So it seems that, for at least our cases, the fix is in 2.6.10 (2.6.9 too?). But Sarge won't be seeing this unless someone makes a backport to Sarge's kernel. Nick //---------------- I was just reading your post at http://lists.debian.org/debian-amd64/2004/09/msg00336.html I'm currently using an MSI K8T Neo-FIS2R motherboard with an Athlon 64 3200+ processor and am using the Debian kernel image 2.6.8-1-k7. When I modprobe powernow_k8, I get """ powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.00.09b) powernow-k8: BIOS error: numpst must be 1 """ which seems to match what you were getting (powernow_k7 says it's not suitable for my cpu). //---------------- (A bit from his reply) > I had to hack the kernel source for that. > in arch/i386/kernel/cpu/cpufreq/powernow-k8.c comment line 639 out: > > return -ENODEV; > > That will make the detection not stop, but continue anyway. //---------------- http://kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.10-rc1 <[EMAIL PROTECTED]> [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.
