The aic7xxx driver is done one of two things:
1) Not setting up the PCI dma mapping correctly for a data
transfer to/from the tape drive.
2) Tearing down a PCI dma mapping too early when doing a data
transfer to/from the tape drive.
It could be that the scsi-tape driver is not setting the data transfer
"direction" field correctly in the scsi commands it generates.
