LOR's on boot

I could not find a PR - I get three LOR on boot, system runs fine.

Filesystem       Size    Used   Avail Capacity  Mounted on
/dev/twed0s1a     97G     29G     61G    32%    /
devfs            1.0K    1.0K      0B   100%    /dev
/dev/twed0s3d    576G    4.0K    530G     0%    /export0
tank             558G    3.2G    555G     1%    /tank

LOR's at end of dmesg.  Stock generic kernel other than:

#cpu            I486_CPU
#cpu            I586_CPU
cpu             I686_CPU
ident           BIG

options         KVA_PAGES=512

nothing in /boot/loader.conf - I load the zfs module and mount that file
system manually.

Thanks --mikej
