Even worse, this problem even manages to make clean rebooting impossible, a= nd I have to use reboot -q instead. It might date back as far as 2005, see: https://lists.freebsd.org/pipermail/freebsd-questions/2005-October/101035.h= tml --=20 You are receiving this mail because: You are on the CC list for the bug.=
