Not really.

mpt0: mpt_cam_event: 0x16       MPI_EVENT_SAS_DISCOVERY

         most likely started

mpt0: mpt_cam_event: 0x12       MPI_EVENT_SAS_PHY_LINK_STATUS
mpt0: mpt_cam_event: 0x16       MPI_EVENT_SAS_DISCOVERY

         most likely done

mpt0: mpt_cam_event: 0x15       MPI_EVENT_IR2

         that could be LD/PD/... state changed

mpt0: mpt_cam_event: 0x21       MPI_EVENT_LOG_ENTRY_ADDED
mpt0: mpt_cam_event: 0x15       MPI_EVENT_IR2
mpt0: mpt_cam_event: 0x21       MPI_EVENT_LOG_ENTRY_ADDED
mpt0: mpt_cam_event: 0x15       MPI_EVENT_IR2
mpt0: mpt_cam_event: 0x21       MPI_EVENT_LOG_ENTRY_ADDED


Giving more details would depend on a subtype which is dependend
on the event.

What we's really need is someone with the specs to write the
code and add the printfs, etc.

Software is harder than hardware  so better get it right the first time.
