BUG kmalloc-16: Object already free
From: Justin Mattock
Date: Sun Sep 28 2008 - 18:54:35 EST
After frying my system, I'm finally up and
running. Not sure if this was due to a git-pull
(only be a few days since the last pull), or what:
when waking from suspend I see this
(I know it says tainted in it, so this will be the only noise you'll
here from me on this);
