:    sched: Keep kthreads at default priority

Strange.  Might be a timing thing bu a) I doubt if any kernel threads
are involved in maintaining a DHCP lease and b) even if they were, such
a race wouldn't be this repeatable.

Maybe it was a bisection glitch.  Did you try reverting just that
patch, see if it fixed things again?
