From today's logs I can see the message appeared some 10 hours ago but the machine is still up & running. I've been running 3.3.0-rc4 for some time now, but network activity went up a few days ago, so that might've triggered it. Ful dmesg & .config: http://nerdbynature.de/bits/3.3.0-rc4/ipv4/ Note: the machine's internal battery seems to be bad, that's why the timestamps during bootup are b0rked in those logfiles.
