Not sure if it could help somehow but at the time it happened I actually traversed some directories in fuse mounted file-system.
Are you still seeing this with 3.7.9 or 3.8.2 in updates-testing?
On a machine I usually observed it I'm using: $ uname -r 3.7.4-104.fc17.x86_64 and hopefully since: $ uptime 16:59:25 up 42 days, 7:11, 14 users, load average: 1.05, 0.79, 0.59 I don't observe this issue nor any other similar problem with the kernel: $ grep -e "Call Trace:" -e :WARNING: -e warn_slow /var/log/messages* | wc -l 0 Thus it seems to got fixed and can be closed.
Thanks for letting us know.
