Hi:

I have problems booting with ACPI enabled. The result varies among three:

1) The kernel will print a number of error messages:

   ACPI-0800: *** ERROR: AcpiEvGpeDispatch: No handler or methdo
       for GPE[ 6], disabling event

   then hang after identifying the hard disk.

2) Same as above, but the messages repeats flickering over the screen
   apparently in an infinite loop.

3) The system boots up, but with seriously reduced performance:

   Booting takes 3min20sec before the login console is presented, and
   building the acpi kernel module takes 54min15sec! With acpi disabled
   booting takes 30sec, and building the acpi module 19sec.

Evidently something is going on,

I beleive it to be hardware conflicts. I have had interrupt storm on
irq5 when configuring the wireless nic which is on irq10 (default), and
on irq7 when moving a connected usb mouse. Usb devices may be found if
attached before boot, although this is no guarantee that they will work.

Another peculiar observation is that it seems to give more consistent
result when acpi is built with debugging on(!).

ACPI however seems to be supported when/if the system comes up: The
device is found and kernel tunables are there. 'halt -p' will halt and
power down the machine.

I built a kernel (GENERIC) with KDB and DDB on, and the acpi module with
debug on. I don't know which is the cause, but doing a command like
dmesg or sysctl results in errors. Such as, for dmesg:

Any clues as to what to do next?

Thanks, Erik
