Hi,

I have neither acpitaskq nor acpi0 in my ps output:

[larse@nik: ~] ps ax | grep acpi
     5  ??  IL     0:00.00  (acpi_task0)
     6  ??  IL     0:00.00  (acpi_task1)
     7  ??  IL     0:00.00  (acpi_task2)

I'm not even sure if this is a bug, or what else it signifies. Happens 
with today's -current, but it probably has been like this for a long 
time (don't even remember if I ever saw those two entries on my system).

The acpi module is loaded at boot, and present in the system. There are 
no errors or warnings in the dmesg output.

(Let me know whether to put kernel config, dmesg, acpidump, etc. If I 
attach them, they'd just get stripped by the mailer again...)

Thanks,
