Comment 1 Michal Schmidt 2008-10-07 13:15:02 UTC
Thank you for the bug report. Try doing this before running latencytop:
echo 1 > /proc/sys/kernel/latencytop
Does it work then?
If yes, I'll push a latencytop-0.4 update to F9. The new version does it automatically.

Comment 2 Fabian Deutsch 2008-10-07 15:07:34 UTC
It helped and I get data when running latencytop.

Thanks.

Actually we should use new keys:
su -c 'yum --enablerepo=updates-testing-newkey update latencytop' 
... maybe this message should be modified for others (!?)
