Hi,

I've just compiled 2.4.20 + the 2002112 patch for 2.4.20rc3 + the cpufreq for
rc3 on my Dell Inspiron 2650 (Mobile P4 1.9GHz. A few weeks work and a few
things don't :)

* I can successfully sleep and wakeup from S1, even while in X, which is 
wonderful. (great to see it working, thanks to everybody who's contributed!). 
However, the screen does not seem to be turned off, only much darker -- I can 
still see the screen albeit darkly when the system is supposedly asleep.

Also, entering S1 means that the system clock seems to stop. For example, if I 
watch the clock on KDE's Kicker, and enter S1, then the system will show the 
same time when it wakes up as when it entered sleep.

Also, the processor fan continues to run even when in S1. The fan stops while 
in standby mode in XP, IIRC, which is what I expect -- the processor is 
halted (I think) so it should cool down, so there's no need t

* dmesg reveals a few errors, whether the are important or not I do not know:

Journalled Block Device driver loaded
    ACPI-1103: *** Error: Method execution failed, AE_AML_REGION_LIMIT

And after having cat'ed a few things in /proc/acpi, the following appears at
the end of the dmesg:

    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT
    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT
    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT
    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT
    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT
    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT

    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT
    ACPI-1103: *** Error: Method execution failed, AE_BAD_HEX_CONSTANT

I'm current using NVidia's propreitary kernel modules, I'd be happy to re-test
with this module not loaded if that is likely to make any difference.

* Reading battery information partially works:

chris@gandalf:/proc/acpi/battery/BAT1$ cat *
alarm:                   unsupported
present:                 yes
ERROR: Unable to read battery information
present:                 yes
capacity state:          ok
charging state:          unknown
present rate:            0 mA
remaining capacity:      3676 mAh
present voltage:         16700 mV

However, the battery is not recognised after removing and reinserting it.

chris@gandalf:/proc/acpi/battery/BAT1$ cat *
present:                 no
present:                 no
present:                 no

* The /proc/acpi/ac_adapter and fan (and possibly other) directories are
empty.


* Slightly OT for here, but controlling the processor speed using cpufreq and
/proc/cpufreq seems to work perfectly, with /proc/cpuinfo reporting that the
speed varies between 1.2 and 1.9, depending whether I ask for performance or
max battery. Whether it actually will increase battery life needs more
investigation :)

I remember there being a acpi->cpufreq patch -- has that been accepted into
the main acpi patch yet? Does the patch only switch between the maximum and
minimum speeds, or other speeds in between, as the SpeeedStep driver for XP
does?

A full dmesg is attached.
