Hi

This is happening to me, too. It starts occuring after about two hours of 
uptime here, and I haven't managed to get any of the sysctl data under this 
effect, as the system will start booting when I run sysctl. sysctl 
dev.cpu.x.freq runs however, showing 400-1200 MHz (with coretemp module 
dev.cpu.0.temperature is 30-35 C) so it's a sensor issue somewhere else - also 
the "overheat" indicator light of the affected box turns on here every ~20 
seconds, causing the fans to run faster.

I've attached the sysctl outputs of the system while it's is running stable. 
powerd is running, with performance_cx_lowest and economy_cx_lowest set to C2.

Also, I've been running 9-STABLE for months (i.e. before and after RELEASE) 
without this issue, but enabled speedstepping only a few days ago, so I think 
this issue might be related to speedsteping. I'll disable it now and report 
back in a few hours if it helped ;)
