dmesg-after-vanilla-kernel-hibernate.out

A bit different with in-kernel hibernate (vanilla kernel, current git), using
the same config.

Hibernate worked the first time. Again, it took a long time hanging at a blank
screen and the computer did not shut off. Yet, after a hard reset, it resumed.
There were no messages in dmesg about ring 5 this time (see attachment).
However, the second hibernation attempt failed. It hang there immediately with
a blank screen, and no image was written. This was with a 3.11-pre-rc1 kernel,
maybe I'll better retest with 3.10 release...
