Well, it's bleeding edge enough, so here's what I've seen so far.

So far, it's been fine, until automountd tried to unmount one of
my filesystems:

Looks like sys_oldumount may be the culprit. I updated mount so we'll see
if it happens again when I reboot it.

I've got some V4L problems too, but they mostly result in the instant reset of the
machine, so it's hard to diagnose anything. (BT driver)
