I don't have got the knowledge Troy likely has got. I already would
have restored my Arch install from a backup. Assumed you don't have got
a backup, I would try a shot in the dark, by installing linux-lts from
the official repositories or linux-rt-lts from Arch audio or use the
downgrade command [1] to downgrade from 3.18.2-2 to 3.17.6-1, just to
ensure that the kernel is or isn't the culprit.
