Author: jhb Date: Mon Mar 28 21:51:56 2016 New Revision: 297366 URL: https://svnweb.freebsd.org/changeset/base/297366 Log: Don't start the random harvester process until timers are working. This is a no-op currently, but in kernels with earlier AP startup, the random kthread was trying to use timeouts with sleeps before timers are working. Wait until SI_SUB_KICK_SCHEDULER to start the random kproc.
