apport information
** Tags added: apport-collected
** Description changed:
After restarting some 'ghost' docker containers on precise with the
raring-lts kernel, the kernel locks up and shows:
[1095015.392057] BUG: soft lockup - CPU#0 stuck for 22s! [gunicorn:12804]
... (for each core)
Here is the original, more docker focused bug report:
https://github.com/dotcloud/docker/issues/3873
I could reproduce this bug with various kernel versions. I've set the
softlockup_panic=1 kernel parameter to get some stack traces. See this
gist for stack trace for 3.5 and 3.8 kernels (will add 3.11 any minute):

- reproduce it in a vagrant VM just our Dell R710 systems so far.
