 The
 kernel dmesg buffer can be preserved over a reboot, so
 it's possible
 the lines up to and
 including "device_attach: re0 attach returned 6"
 are
 from the reboot before you installed the
 patch.  Rather than just grep for
 re0, do
 "dmesg | less" or "dmesg | more" and
 check the context of the 
 "device_attach: re0 attach returned
 6" error and see if there are any 
 indications of a reboot between that line and
 the next re0 probe lines, e.g.
 "Copyright (c) 1992-2015 The FreeBSD
