I've been trying for about a week now to get acpi working properly on this
machine (using 2.4.21-pre5 and the latest acpi patch) but im just not having
much luck. The annoying problem is the fan. The fan comes on as it should,
but then it will never go off again. The fan is "detected" and shows up under
/proc/acpi/fan/FAN/ and under /proc/acpi/power_resource/PFAN/. Both of these
directories have a "state" file which show:
mark@... /proc/acpi/fan/FAN]$ cat state
[mark@... /proc/acpi/power_resource/PFAN]$ cat state
system level: S0
reference count: 0
"echo 0 > /proc/acpi/fan/FAN/state" shows the following:
acpi_power-0363  acpi_power_transition : Error transitioning device [FAN]
acpi_bus-0496  acpi_bus_set_power : Error transitioning device [FAN] to
"echo 1 > /proc/acpi/fan/FAN/state" shows:
acpi_bus-0447  acpi_bus_set_power : Device does not support D1
/proc/acpi/power_resouce/PFAN isnt writable.
cat /proc/acpi/event will properly show when the lid switch or power button is
battery info doesnt appear to be read correctly as it shows a battery even
when i remove the battery. (doesnt bother me)
thermal info appears to be read correctly (temp goes up and down with system
the fan problem is the only thing that is really bothering me (the fan is
loud!!). i've tried to create my own dsdt file with no luck. in the stock
dsdt file Device(FAN) appears to be an alias to PowerResource PFAN.
i've searched the net over and cant seem to find any info on this laptop and
any help or tips would be greatly appreciated!

I'm still having trouble with the latest acpi patch and 2.4.21-pre5. The
problem is once the cpu fan comes on it will never go off again. Disabling
acpi will correct this problem but then closing the lid will cause the
machine to hard lock requiring a cold restart. Acpi is correctly reading the
state of the lid and power button, thermal zone seems to work, sleep doesnt
seem to work as it should but this doesnt bother me. Battery info appears
incorrect as it will show a battery even when the battery is removed. Ac
power is correctly read.
I would greatly appreciate any help!! Compiling acpi without fan support
doesnt help, the fan still gets stuck on. Is there anyway around this other
than disabling acpi completly causing the lid switch problem?

Look at thermal zone info, try echo 3
> /proc/acpi/fan/PFAN/state (IIRC).
