   ...nasty rumors. :-) The port of CAM to 2.2.x that Justin did was sort of
a favor to me; I was having an intermittant problem with 'buffer already
done' panics that appeared to be a buffer mismanagement in the (MI/MD) SCSI
layer, and we thought it would be interesting if the problem went away by
using CAM (it did!). I did ask Justin at the time if it would be possible
to make both the old and new SCSI system available as compile-time options,
but this is difficult due to serious namespace conflicts and incompatible
software interfaces. I don't think a patchkit of somesort is out of the
question, however...but you'll have to do some arm twisting (Justin's arm,
not mine! :-)).
