[Bug 979696] [NEW] apt-get check apparently consuming CPU leaving instance unusable

[Michael Nelson]

Public bug reported:

Each morning I have trouble ssh'ing into a precise instance which I have
running (on canonistack). After several minutes I am able to get to a
shell and run `top` which shows apt-get consuming the CPU (load went
over 18).

Rebooting the instance certainly helped yesterday, but since it happened
again, I've tried to collect the info:

grepping for the actual process processes shows me (`ps fax | grep apt-
get`)

24417 ?        D     18:56                  \_ apt-get check -f -qq

I had to kill 24417 before `ubuntu-bug apt` would progress.

Let me know if there are other logs to attach.
