F10/rawhide kernel needs kacpid/kacpi_notify resume fixes
Last modified: 2013-01-09 23:54:20 EST
The problem with kacpid/kapci_notify consuming the CPU upon ACPI resume, reported against F9 (in bug 451399), also affects Rawhide kernels and thus F10.
This bug has been fixed in the latest F9 updates-testing kernels, but still has not been fixed for rawhide/F10.
Since this will effectively be a regression by the time F10 is released, I'm updating this to a blocker...
Is this likely to be resolved. I'm still seeing this in the pre-release? I can test an update if needed.
All the updates from the f-9 updates-testing kernel plus the two updates that went in 220.127.116.11-29.fc9 are in kernel-18.104.22.168-89.fc10
kernel-22.214.171.124-92.fc10 should be in tomorrow's rawhide, please test it then.
Tested kernel-126.96.36.199-92.fc10 on my Dell Latitude D820, kacpid/kacpi_notify still consume CPU after resume.
I tested 188.8.131.52-94; as Magnus reported for 184.108.40.206-92, kacpid/kacpi_notify
still consume the CPU after resume.
Same here, no joy on .5-94.
Fails retesting. Gonna need to give this another look, I guess.
Keep in mind that this does not interfere with installation, nor corrupt data, and we can fix it with a post-F10 update. If we can't get a satisfactory solution we probably won't block the release for this.
Since we wouldn't block release, -> Target.
I've tested kernel 220.127.116.11-109.fc10.i686 on my Dell Latitude D610 notebook and both ACPI related problems are solved:
1. suspend/resume works fine, kacpid/kacpi_notify don't trash the CPU anymore
2. undock/dock works without any problems, no kernel crashes anymore
No joy for me still. My CPU still gets loaded up after suspend with the latest kernel.
On my Dell Latitude D620, with 18.104.22.168-109, kacpid/kacpi_notify still trash the CPU after a resume.
I don't agree with changing this bug from F10Blocker to F10Target. Having non-functional ACPI suspend/resume is a critical bug, especially for mobile devices. If F10 is kicked out the door with this bug still present, I think it's going to make a very bad impression for users of mobile devices who are affected by it.
I will look at the overall patchset that fixes the kacpid/kacpi_notify bug again and see if I can't isolate out just the bits that address the kacpid/kacpi_notify bug, without the hot [un]docking features.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
This was also in bug 454954 against F8. Problem still occurring on Dell Latitude D600 on 22.214.171.124-117.fc10.i686.
Please try kernel-126.96.36.199-30 from the updates-testing repository.
188.8.131.52-30 seems good to me.
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '10'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 10's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 10 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
