[Reuben Thomas <rrt@xxxxxxxx>]

After experiencing a variety of nasty crashes, I stopped using suspend
altogether (I tried upgrading to the utopic kernel, without benefit).

I've just tried using hibernate instead (note, this is disabled by
default in Trusty, at least, but can easily be reenabled, e.g. see

http://ubuntuhandbook.org/index.php/2014/04/enable-hibernate-
ubuntu-14-04/

) and it seems to work better: no pause before hibernate, and no kernel
oops messages when I resume. Of course it's a bit slower, but it's an
acceptable workaround until the bug is fixed.
