From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.1) Gecko/20060313 Fedora/1.5.0.1-9 Firefox/1.5.0.1 pango-text Description of problem: kacpid does not always trigger on a powerfail signal shorter than 125 msec and never if the signal is shorter than ~95 msec. This is important since there is usually time to at least save buffers and sync filesystems on the remaining capacitor charge in the power supply. The power supply in some small systems delivers a powerfail signal with a duration of 100 msec +- 10 msec. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.send power button signal generated at 90 msec... nothing happens 2.send power button signal generated at 100 msec... power down sequence starts 30% of the time 3.send power button signal generated at 125 msec... power down sequence starts every time Actual Results: Expected Results: Additional info:
This is kernel acpi related though, so i'll reassign it to the proper component. Read ya, Phil
there's absolutely no guarantee that kacpid is going to be scheduled in any given timeframe.
