[Solved] Powertop not finding Model-Specific Registers?

I just updated my machine, I didn't see powertop in the list of programs to be updated, but I could've missed it. I don't think I spotted any errors while updating, either. When I tried to run powertop, however, this was the output:

After outputting this chunk of text, the program would stop. I'm not entirely sure what Model-Specific Registers are, I'm reading up on them in wikipedia now...

Any thoughts?

EDIT: If it's helpful, I am running on a Thinkpad X201, and have not had any issues with powertop (or anything else, really.) until now.

Re: [Solved] Powertop not finding Model-Specific Registers?

Well, I restarted, and that seem to fix it. I'm not sure what it was, though. On another note, now my KDE effects are not working - I'm not sure if it's related, so I'll make a new thread for that.

EDIT: Here is the other thread I started, if you're interested: https://bbs.archlinux.org/viewtopic.php … 7#p1402517
