blocked tasks delay cloud-init for 240 seconds

Bug description:
Binary package hint: cloud-init
Running tests for lucid rc, I came across one system that was not
accessible via ssh.
The console collected after waiting ended like:
| [ 1.036270] Freeing unused kernel memory: 216k freed
| [ 1.037531] Write protecting the kernel text: 4288k
| [ 1.037892] Write protecting the kernel read-only data: 1324k
| init: console-setup main process (62) terminated with status 1
| %G
Because this was an ebs root instance, a shutdown was run, and console
collected after that. I will attach that full console log. The
interesting subsequent output was:
| %G[ 240.805451] INFO: task apparmor_parser:182 blocked for more than 120
seconds.
| [ 240.805466] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables
this message.
| [ 240.805581] INFO: task mount:209 blocked for more than 120 seconds.
| [ 240.805587] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables
this message.
| [ 240.805683] INFO: task flush-8:1:232 blocked for more than 120 seconds.
| [ 240.805689] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables
this message.

It appears that something apparmor related blocked for 240 seconds,
which ran past my time alloted for boot and ssh connection. The
system *did* come up, but in a much longer time frame than normal.
