Description of problem:
kerneloops process uses ~90% CPU
Version-Release number of selected component (if applicable):
always after startup
Steps to Reproduce:
2.check processes with top or listen to the sound of the CPU cooler...
kerneloops eats CPU
kerneloops NOT eats CPU
How big is your system log file? (/var/log/messages)
That log is huge because now it's full of drm error messages. I don't know how big it was when I reported the bug and I removed kerneloops. But maybe the size of the log was the cause.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
I have the same issue on one of my laptops. After log in kerneloops CPU usage goes up to 100%.
removing kerneloops applet from session might help, but when switching to another user fires up it again and cpu goes up again :)
More information here:
This starts occuring on one of my computer after upgrading to Rawhide -- exact same problem, with drm_wait_vblank.
This happened with me also, killing kerneloops' process and removing the messages file made the issue stop happening.
for current status. If kerneloops acts up again I will see if strace can get anything.
Kerneloops had another tantrum got strace of the issue this time. I am attaching it to this bug. hope it helps.

ran strace while kerneloops was hogging the cpu's
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. 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bug reports from releases that are no longer maintained.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 '11'.
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 11'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 11 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 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.
