Description
This is gcc4 build of hrev36566 on Acer Aspire One 150 (Intel Atom n270).
I get the error when opening the CPUFreq-Pref-App or using the CPUFreq-Replicant. I can reproduce this 99%.

SpeedStep driver has been removed as it didn't support any CPUs with invariant TSC and didn't work on SMP systems.
Note:
See TracTickets
for help on using tickets.
In x86_write_msr(). Most likely your CPU doesn't have/support the MSR in question. The driver might not correctly check that.
