shutdown problem : acpi_power_off freeze

[Bruno Costacurta <pubmb.bco@pt.lu>]

Hello to all,

when I shutdown my computer it doesn't turn off but freeze with the 
message 'acpi_power_off called'.
However the shutdown was working before I re-config my ALSA sounds (via 
alsaconf) and indeed I have a vague remember reading something in the past 
like acpi has / have some problems with alsa which might block a complete 
shutdown like in my case.

acpid seems correctly start :

ps -ef | grep -i acpi
root        15     9  0 11:57 ?        00:00:00 [kacpid]
root      2890     1  0 11:57 ?        
00:00:00 /usr/sbin/acpid -c /etc/acpi/events -s /var/run/acpid.socket
105       2911  2903  0 11:57 ?        00:00:00 hald-addon-acpi: listening on 
acpid socket /var/run/acpid.socket

Thanks for reading and/or any help

Bye,
Bruno
