Re: ichss0: transition to 1 failed

Hi.

I got this problem solved thanks to Bruno Ducrot who emailed me offline providing a patch for sys/dev/cpufreq/ichss.c to autodetect CPU's that don't support SpeedStep technology.
Just like my Pentium Celeron M.
It could also be fixed with following string put to my /boot/loader.conf to disable ICHSS:
hint.ichss.0.disabled="1"

And est does not work, but p4tcc does.

For the record:
There are no occurances of ichss in sysctl now.
