Description Nicolas CAZIER 2005-05-02 08:46:56 UTC 
Distribution:Debian testing + debian "unstable" kernel 2.6.11-1
Hardware Environment: asus V6V notebook (i915pm + Dothan 1.73 )
Software Environment: 
Problem Description: when loading battery kernel module, events seem to be
pooled in a queue (exception : power button, and LID )

Exemple : After loading battery module, the next acpi event (button other than
PWR or LID) does not appear. Sending sevreal events (between 2 to 8 !) while
make the first event be send to acpid (or /proc/acpi/event).

Actions on battery seems to "pool" invisible events to the queue : 
exemple : Send an event to ACPI. It does not appear (as expected). Read several
times the /proc/acpi/battery/BAT0/info or state file (between 2 to 8) the event
is send to acpid (or /proc/acpi/event). 

As said : PWRB and LID are not impacted. but SLEEP button is (Fn + F1). All
other events are impacted.

Steps to reproduce: shutdown acpid, modprobe the battery module and start
playing around whith acpi events (Fn + buttons, AC unplugging ) while monitoring
event file.

still an issue in 2.6.13?

I have the same issue with kernel 2.6.12-12mdk (Mandriva kernel). I have an Asus
M6Ne notebook.

With fresh 2.6.13.2 kernel unpatched, it still isn't fixed.
But with 2.6.13.2 + acpi-20050902 patch, it works fine.

With older kernel, the solution was to compile with Preemptive kernel and HPET
Timer Support enabled in kernel, but with 2.6.13.2 + acpi-20050902, preemptive
kernel is no more needed.
