--- Comment #6 from trond.endres...@ximalas.info ---
Good news everyone! I've recompiled r346627 with options INVARIANTS and options
INVARIANT_SUPPORT, and I simply wanted to return to singleuser mode when this
happened.
Unread portion of the kernel message buffer:
<118>[797] Stopping rpcbind.
<118>[797] Waiting for PIDS: 884.
<118>[797] Stopping devd.
