The offending section of pci-dma.c identifies itself as "temporary 2.4 hack", so I'm guessing the problem lies there. :)
The pci-dma code is fine. It's either the driver or the SCSI tape driver passing an illegal scatter-gather list.
256k blocksize works fine in 2.6.3-rc2. I can't just run that version because the 3ware driver seems to be just totally broken in 2.6 (first access seeks the drives then freezes the machine, no message, no nothing). But you guys aren't in the 2.6 game so you don't have to solve that problem. ;-)
3ware works for me fine on 2.6 This means on some boxes with iommu on it seems to trigger MCEs, but these can be disabled. -Andi
