Powernow issues on Athalon 64

[Philip Prindeville]

I'm running FC3 (2.6.12-1.1378_FC3) on an Athalon 64 (2800+)
with an MSI K8MM-V motherboard...  And seeing:

powernow-k8: detected change pending stuck
powernow-k8: transition frequency failed
powernow-k8: failing targ, change pending bit set
powernow-k8: failing targ, change pending bit set
powernow-k8: failing targ, change pending bit set
powernow-k8: error - out of sync, fix 0x2 0xa, vid 0x0 0x0
powernow-k8: ph2 null fid transition 0xa
powernow-k8: detected change pending stuck
powernow-k8: transition frequency failed
powernow-k8: failing targ, change pending bit set
powernow-k8: failing targ, change pending bit set


Is this a known issue and is there a fix for it?

Thanks,
