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.
