Red Hat Bugzilla – Bug 416511
Kernel 'hangs' when using mouse/keyboard after short break.
Last modified: 2009-01-09 00:27:24 EST
Description of problem:
The new kernel update (kernel-126.96.36.199-63.fc8) causes my system to 'hang' when I
leave it alone for a couple of minutes, then press a key or use the mouse.
Everything freezes for about a second (i.e no video update), then the screen
updates and the cpu meters show full usage (when there was none before) and the
logs shows messages like;
Dec 5 16:55:08 echo kernel: psmouse.c: GlidePoint at isa0060/serio1/input0 lost
synchronization, throwing 2 bytes away.
Dec 5 16:55:12 echo kernel: psmouse.c: resync failed, issuing reconnect request
It can take a few seconds for the system to recover. Reverting back to the
kernel-188.8.131.52-49.fc8 version fixes this problem.
I have a dell inspiron 8500 laptop.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Leave machine alone for a couple of minutes.
2. Try moving mouse or pressing a key
System freeze/hang for a few seconds with a cpu spike
Immediate response, no cpu usage spike.
Same problem with kernel 184.108.40.206-85.fc8.
However I have discovered that the gnome-power-manager "Dim display when idle"
triggers this problem.
This feature does not work on my Inspiron 8500, however when a stuck the hard
drive into a Latitude D800 to test some other issues, the screen actually did
dim and there was no such problem.
Unchecking the dim when idle feature solves my problem back on my inspiron.
I'm not sure whether the problem really is the kernel, however the older
versions did not exhibit this problem when the dim when idle feature was
enabled. Both machines had the same graphics card (nvidia go 4200) so would have
been using the same X driver.
Unfortunately, while the dim when idle does seem to have helped, it has not
completely resolved my problem. I am still getting the "hangs" when idle for
some undetermined period of time. It does, however, now seem to be a longer
period of time.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. 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bug reports from releases that are no longer maintained.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 '8'.
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 8'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 8 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 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
