CPU governor fails to set frequency on Atom 230

Weapon S · 03-15-2013, 06:20 AM

CPU frequency stepping seems to be unavailable. Boot messages says that governor failed. dmesg Doesn't say anything funny, except that there is a "PSE erratum" and I need to upgrade my BIOS. I hope this is unrelated, because there seems to be only a very laborious way to update the microcode, but I am not sure that will solve the problem.
I couldn't find what PSE is, so I'm not sure it is related.
Is there anything I can check before I try the PSE fix? I'm on Debian Squeeze. I'd like to avoid kernel compilation.

According to this, https://bugs.launchpad.net/ubuntu/+s...ts/+bug/736142, you need the p4_clockmod kernel module.

Thanks. I'll look into it.
