Re: ACPI events dead after suspend / resume in 3.x

Hi Nigel,

This is the same issue I've been having since 3.0 (.29 works fine).

My thinkpad forgets all FN keys after resume from hibernation.
Suspending to RAM appears to bring them back. I have tested a few
patches (see our previous conversation on this subject) but have been
unable to find the culprit.

Please let me know if you need my help to test anything.

Regards,
Pedro
