Comment 1 Damian Wrobel 2012-10-03 07:55:20 EDT
Not sure if it could help somehow but at the time it happened I actually traversed some directories in fuse mounted file-system.
Comment 2 Josh Boyer 2013-03-12 15:45:04 EDT
Are you still seeing this with 3.7.9 or 3.8.2 in updates-testing?
Comment 3 Damian Wrobel 2013-03-13 12:09:11 EDT
On a machine I usually observed it I'm using:

$ uname -r

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

Thus it seems to got fixed and can be closed.
