From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b4) Gecko/20050914 Fedora/1.5b1-0.fc3 Firefox/1.4 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.
Change reproducibility to "some times"...
This is a mass-update to all currently open Fedora Core 3 kernel bugs. Fedora Core 3 support has transitioned to the Fedora Legacy project. Due to the limited resources of this project, typically only updates for new security issues are released. As this bug isn't security related, it has been migrated to a Fedora Core 4 bug. Please upgrade to this newer release, and test if this bug is still present there. This bug has been placed in NEEDINFO_REPORTER state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. Thank you.
Haven't seen this in a while, so it's probably safe to assume that things are fixed now... Especially since ACPI state of FC4 is actually pretty solid right now!
