Public bug reported:
When I connect the ac power in my laptop (sony vaio vgn fs415M and Hardy x86)
my cpu speed doesn't adjust to cpu power management settings (power management
preferences -> on ac power -> computer speed policy -> always maximum speed),
that is to maximum speed but still remains to "based on processor load" as it
shouldn't have ac-power plugged in (but the battery icon in the status bar
changed indicating that is in charging state, so the ac-power was detected).
However if I reboot the system with ac-power plugged-in the cpu is at correct
speed (that is at maximum speed).
I see cpu speed with "cpu frequency scaling monitor" applet (version 2.22.2) or
with "cat /proc/acpuinfo"
The same thing happens if I am in the contrary situation (that is I start with
ac-power plugged in and then I plugged out ac-power and my cpu freq is always
at maximum speed).
I say first that I enabled "computer speed policy" option in power
management preferences via gconf-editor as the gui hasn't this option
from default (I think this is a thing to fix in next distros as well as
in Hardy)
Linux kernel "Linux cheope 2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21
