Note that hte problem exists in 1.5.X.

Why do you think that this is wrong?

If I get either EAGAIN or ENOMEM from dma mapping, I return an internal
CMD_EAGAIN. This normally sets the error to XS_RESOURCE_SHORTAGE and does a
channel freeze and calls scsipi_done, which is correct. The setting to
HBA_BOTCH is in case this is a *POLLED* command, where it would be correct to
fail the command.

This is better than what it was doing before (which was nothing). Why is this
in error and what is your basis for saying this rev 'broke' things?

If you have help to offer great. If you're swamped, don't fire from the hip-
it's just annoying.
