dmesg trace of problem
With kernel-2.6.17-1.2364.fc6, I am getting a message related to cpuspeed that
looks similar. This is not an smp machine and does not see to be related to the
NIC. I will attach my cut from dmesg for comparison.

Attachment with output from dmesg
This seems to be more cpu speed realted but the frequency control seems to work
should be fixed in tomorrows rawhide push (kernel-2.6.17-1.2375.fc6 or higher).
Created attachment 132514 [details]
still seeing this with kernel-2.6.17-1.2401.fc6
The error still seems to be present.
I don't think his has anything to do w/ orinoco...looks like cpufreq to me...
