Commit 1b7fc5aae8867046f8d3d45808309d5b7f2e036a causes my Thinkpad T21
to no longer generate any hotkey events (e.g. suspend fn-f4, switch-output
fn-f7, etc.) after resume.
It's regression from 2.6.25. 2.6.26 and 2.6.27-rc7 are broken,
reverting that commit on 2.6.27-rc7 makes keys work again.
Thanks.
[Rafael added for regression tracking ;]
