Bruce,

  Please do us a favor, these kinds of reports basically go into the
bit bucket when posted to the freebsd-questions mailing list.

  If you would be so kind, please run send-pr on your 4.11 systems
and send what your seeing in as a bug.  Granted, since it's not
specific nobody is going to be able to send you a patch or some
such - but there is still value in these reports being in there as
if others report the same trouble a coorelation can be drawn.

  Also please list the model number of your SuperMicro motherboards.

Thanks!
Ted
