I'm not quite sure how to do that - I've enabled CAMDEBUG and set CAM_DEBUG_FLAGS=CAM_DEBUG_INFO|CAM_DEBUG_CDB - do I also need to set CAM_DEBUG_(BUS|TARGET|LUN) to get debug from boot? I tried a boot -v, and it shows the following: (probe1:mpt0:0:1:0): MODE SENSE(06). CDB: 1a 0 a 0 14 0 (probe1:mpt0:0:1:0): ILLEGAL REQUEST asc:24,0 (probe1:mpt0:0:1:0): Invalid field in CDB (probe1:mpt0:0:1:0): INQUIRY. CDB: 12 1 80 0 ff 0 (probe1:mpt0:0:1:0): ILLEGAL REQUEST asc:24,0 (probe1:mpt0:0:1:0): Invalid field in CDB Not sure if that is relevant or not. Also, there was an "mpt0: soft reset" - unfortunately, I haven't got physical access right now so I can't do a full power cycle. Does that make a difference? -- Best Regards Kenneth Schmidt
