Re: Who's playing with scaling_max_freq?
You might need to relaunch :
invoke-rc.d cpufrequtils restart
or maybe :
or something around this (at the top of my head).
Hope that helps.

Objet: Who's playing with scaling_max_freq?
Max scaling_max_freq seems stuck at 1GHz even though it should be able
to go up to 1.83GHz.
# echo 1833000 >/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq; cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
1833000 1333000 1000000
This is on a Thinkpad T60 running Debian stable. Any idea what might be
causing this? Or at least, which part of the system might cause
scaling_max_freq to be (re)set to 1GHz right after I force-set it to 1.83GHz?
Would it be some daemon like systemd or rather than kernel?
This Thinkpad T60 is actually used as a desktop: it's parked in a dock
(with the lid is closed) where I have it connected to a keyboard and monitor.
