Solved (Re: FYI: acpi | boot hangs when Laptop not connected to AC | NEC Versa FM320)

[Matthew Dillon]

:Works, for met too!
:I noticed the following behaviors:
:The message "Performance set to economy" is no longer visible at boot 
:(which IMHO is favorable).
:The laptop is off line noticeable slower then on line but the 
:throttle_state's are the same (hw.acpi.cpu.throttle_max: 8, 
:hw.acpi.cpu.throttle_state: 8) plugging the power cord in doesn't make 
:the laptop faster, when once booted off line.
:I seem to fail to discover which sysctl to tweak to get it at full speed.

:Thanks you (and all the other contributers offcourse) for the excellent 
:work, I really appreciate it!

    The same thing happens to me, except it does tell me that the system
    power profile has change to 'economy' on boot (maybe it tells you too
    but you aren't looking in the dmesg in the right place).  And, indeed,
    when I power up with the AC unplugged the machine runs at half speed,
    but then does not speed up again when I plug the AC in (even though it
    tells me it has changed to 'performance' mode).

    Similarly if I power up with AC plugged in (the machine goes full speed),
    but then if I unplug the AC after the system has come up it doesn't slow
    down at all even though it tells me that it has switched to 'economy'
    mode.

    So I think that whole section of code is misbehaving in both directions.
    I expect there is some sort of ACPI method that must be run that isn't
    being run.

    Maybe one of the other developers can suggest things to try.
