Bug Description
Output of command "time sudo mount /dev/sdc1 /mymount":
real 10m46.175s
user 0m0.000s
sys 10m44.488s
Some recent threads on the web indicate that other user(s) have observed this issue in the context of large ext4 systems, and that the issue is specific to kernel 3.2.0-30-generic. Those threads indicate that the issue is resolved if the user reverts to a previous kernel. Unfortunately I'm not in a position to confirm this on our server.
In my case, the relevant file system itself is reported as "clean" by fsck.ext4.
Please let me know if I can provide any diagnostic output of interest.
