I'll handle this.

  Dell Poweredge 2450's with Adaptech 2940 U2W controllers.  Channel
  2 of the raid array is mapped to logical drive 0 on id 8, and
  channel 3 of the raid array (4 channels 0-contoller cache, 1 drive
  array, 2 host 1, 3 host 2) is mapped to logical drive 1 on id 10.
  The first host will boot fine when connected to channel 2, but the
  second host will fail when connected to channel 3 of the raid array.
  I get the following error after hitting F1 FreeBSD (FreeBSD boot
  manager):

It would probably be useful if you could send the following output

    dd if=/dev/mem bs=1024 skip=816 count=16 | gzip > foo.gz

(best send it to me directly rather than the whole list).  A division
by zero exception is apparently happening, and the output may throw
some light on this.

Thanks for the feedback.  The kind of error made me wonder if it
wasn't a more general problem than just BTX, and I think it makes
sense to close the PR in the light of the additional info.

State Changed
From-To: open->closed

From further information gathered by the originator, it seems most 
likely this is a hardware or firmware problem.
