1 After a reboot, cpuinfo returned normal values... for a while.

3 My best guess so far is it some how relates to the cpufreq governer.As of
4 2.6.14, changing between performance and userspace seems to hose up the
5 clock values in cpuinfo.

7 At the moment it is using the userspace governor (powernowd) and returning
8 between 7 and 14 GHz and 15-28k bogomips. So, I'm inclined to think this is
9 a kernel bug. The available clock speeds should be between 500MHz and 1.5GHz
10 .
11
12 I'm going to reboot again and experiment a bit to see if I can nail down
13 what triggers the abberation.
