The sequencer code (and all of the CAM code for that matter) are kept
in a private Perforce repository until everything is ready for inclusion
in the FreeBSD-current. Here's a patch to revert the only sequencer change
that applied to the aic7890. It does touch the other DMA fifo, so
perhaps it is indirectly causing this problem.
