This is because the packet driver tries to send down read/write BLOCK_PC commands that don't use a bio and do not use sg lists. As part of the patch you mentioned I added strict assertations for that case because the scsi layer doesn't handle those anymore.
The right fix is to replace all the packet_command stuff in the packet driver by scsi_execute() which needs to be lifted from scsi code to the block code for that. I'll prepare a patch this weekend unless someone beets me in doing that work. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
