Acpid won't start at boot anymore

[Goulven Guillard <lecotegougdelaforce@free.fr>]

Hi,


Since I upgraded to Xorg 6.9 under FC4, I have an acpi problem.


First, during rhgb (Fedora's graphical boot interface, which uses X), I 
had the following error :
acpid : can't open /proc/acpi/event (device or resource busy)


I thus tried several things, like disabling the acpid service at boot 
and launch it in /etc/rc.d/rc just after the exit of rhgb, etc. However, 
even when it is completely disabled, the same error still appears in 
/var/log/Xorg.0.log :
(WW) Open ACPI failed (/proc/acpi/event) (Device or resource busy)


When gnome is launched, the /proc/acpi is full of acpi features like 
thermal_zone, battery & cie, though. But launching the "battery charge 
monitor" gnome applet fails : I have for this to start the acpid service 
by hand (which works fine, no error message !).


So, does anybody have a solution to start the acpi daemon automatically 
at boot ?


Thanks.
