Public bug reported:
I have extreme swapping which turns my notebook unusable. Looking in the logs I
find messages related to swapping after the following lines:
Dec 10 11:07:45 ubuntu kernel: [89143.980050] wlan0: no IPv6 routers present
Dec 10 11:21:07 ubuntu kernel: [89945.467868] swapper: page allocation failure.

During a week I always use suspend instead of shutting the notebook down. It is
currently running for two days which should not be a problem.
