I had been finding my system in deadlock (kernel running, responding to
pings, but unable to do any user level stuff). My system was swapping, but
not a hell of a lot, and doing a bunch of file access.
It looked like a disk or a vm thing, and the PR sounded like it fit. So I
applied the patch and it has seemed to help. It's only been a few days, so
I'm not willing to say it has been fixed 100%.
