Problem Description:

The new "acpi_wake_gpes_always_on" kernel option didn't work. Without these
the LID switch on my laptop did not work any more (has worked with
2.4.25 and apci patches)

As you can see from the attached dmesg output, the kernel option
is recognized:
Apr 17 01:14:53 localhost kernel: ACPI: wake GPEs not disabled

But later on, there are wake GPEs found:

Apr 17 01:14:53 localhost kernel: evgpeblk-0926 [06] ev_create_gpe_block   :
Found 2 Wake, Enabled 1 Runtime GPEs in this block

If I understand linux-2.4.26/drivers/acpi/events/evgpeblk.c correct,
alls gpe are initialised as ACPI_GPE_TYPE_RUNTIME and in line 879ff only if the
"acpi_wake_gpes_always_on" kernel option is not set the GPEs are checked if they
have to be changed to ACPI_GPE_TYPE_WAKE -- so with this option set there should
be no wake GPEs.

Just guessing: maybe acpi_ut_init_globals() is called after 
acpi_wake_gpes_always_on_setup() ?

Thanks for all the work on acpi linux code.

We will release a improved wakeup/runtime GPE implementation soon. 
Thanks,

This was fixed early on in 2.4.28: 
http://linux.bkbits.net:8080/linux-2.4/cset@411d887a5dK6KUykwxHohbB0vxJssw 
and is also available in the 24-stable-release ACPI patch for 2.4.27. 
 
closing.
