BTW, looking at the Promise code I see
cam_con.h: /* for ASIC bug, limit the last element of SG byteCount must < 32 Dword */ #define SG_COUNT_ASIC_BUG 32 //#define SG_COUNT_ASIC_BUG 128
and in the code itself
/* check PRD table, last element <= (32 Dword), fix ASIC bug */
(though the code obviously uses SG_COUNT_ASIC_BUG==32, as the first paste indicates)
so it seems like Promise first used 128 (32 dwords), but then backed down to 32 (8 dwords).
Either way, we definitely have an ASIC bug to work around, it seems... Jeff - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
