Description James 2008-04-13 22:09:03 UTC
Description of problem:
ACPI subsystem does not generate events for laptop lid or power adapter.

Version-Release number of selected component (if applicable):
kernel-2.6.24.4-64.fc8

How reproducible:
Always.

Steps to Reproduce:
1. Put down lid, or change power adapter state.
2. Notice it doesn't suspend.
  
Actual results:
/proc/acpi/button/lid/LID/state reports the state of the lid correctly, as does
/proc/acpi/ac_adapter/AC/state with the AC adapter. However

$ acpi_listen

doesn't report any events.

Expected results:
Lid events generated.

Additional info:
dmesg and acpidump output attached.

Extra info: the sleep button is found but doesn't work, either. Tried
acpi_osi=Linux as it is defined in the DSDT, but that doesn't seem to change
anything.

Fixed in kernel-2.6.24.5-87.fc8.

Comment 5 James 2008-05-23 19:40:28 UTC
Correction, make that kernel-2.6.24.7-92.fc8. First noticed in
kernel-2.6.25.4-10.fc8...

Comment 6 James 2008-05-23 20:43:27 UTC
Hello, sorry to keep changing this... it seems like it was actually fixed in
kernel-2.6.25.4-10.fc8. I think this must've somehow configured the EC so that
events did get generated, and whatever was changed persisted across a reboot.
When I booted kernel-2.6.24.7-92.fc8 from cold, the events are no longer received.
