Description of problem:
sometimes, ACPI events fail to make it to /proc/acpi/event, or acpi breaks down completely in the kernel(?). This SEEMS to happen particularly after suspend to mem (echo -n mem > /sys/power/state).

This is what happens...

If I stop the acpi daemon for testing, then start "cat /proc/acpi/event" to watch the messages and then start generating ACPI events, the results are unstable.

Sometimes i'll get the events normally. Sometimes, i won't get them at all and yet other times, i'll get the first few events and then no more.

I have been able to get things working again by reloading the ac and battery modules, but again, this does not work every time.

I guess this problem is related to the major ACPI changes from 2.6.11 to 2.6.12 somewhere.

If you don't have all the info, ask and i'll provide! :o)

Version-Release number of selected component (if applicable):
kernel-2.6.12-1.1378_FC3

How reproducible:
Always

Steps to Reproduce:
1. Resume machine from suspend to memory
2. service acpid stop; cat /proc/acpi/event
3. generate acpi events (un/re-plug power, hit various acpi keys)
  

Actual Results:  Sometimes no events will show, sometimes no more than a few.

Expected Results:  Events should be delivered reliably every time an event is generated.

Additional info:

My machine is an IBM ThinkPad T30 (2366-JBG), i've built an ibm_acpi module from the source from ibm-acpi.sf.net but the problems happen even without the ibm_acpi module.
