The is still running, I just noticed a short hickup, probably when it was busy writing the warning to the disk. More details and .config: http://nerdbynature.de/bits/2.6.23-rc5/ I'm not really sure what the application mentioned in the message above has to do with this: the application[1] has been running since bootup as a non-privileged user and did so for earlier kernel versions too.
