Remove the flags from sio1 in your config file & rebuild your
kernel.

Eg:

This is left over from using sio1 for kernel debugging years ago.
I'll see if I can get it yanked before the next release.  Its already
gone in -current.

-STABLE *is* 4.8-PRELREASE.  It will branch at the time of the
release, until then, its RELENG_4.
