When the linux port changes were imported which split the target command list to be separate from the initiator command list and the handle format changed to encode a type in the handle the implications to the function isp_handle_index (which only the NetBSD/OpenBSD/FreeBSD ports use) were overlooked. The fault is twofold: first, the index into the DMA maps in isp_pci is wrong because a target command handle with the type bit left in place caused a bad index (and panic) into dma map. Secondly, the assumption of the array of DMA maps in either PCS or SBUS attachment structures is that there is a linear mapping between handle index and DMA map index. This can no longer be true if there are overlapping index spaces for initiator mode and target mode commands. These changes bandaid around the problem by forcing us to not have simultaneous dual roles and doing the appropriate masking to make sure things are indexed correctly. A longer term fix is being devloped.
