I'm seeing the strangest thing with my M1015/LSI card. I'm getting regular DID_BAD_TARGET errors in the kernel log for a drive that was erroneously detected.
Inital detection looks like: [ 0.860853] megasas: 06.806.08.00-rc1 [ 0.860877] megasas: 0x1000:0x0073:0x1014:0x03b1: bus 1:slot 0:func 0 [ 0.861172] megasas: FW now in Ready state [ 0.861796] libata version 3.00 loaded.

Two of the ports on the card are unpopulated. Then I see some errors some time later: [ 7113.505094] sd 0:0:14:0: [sdi] FAILED Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK [ 7113.506044] sd 0:0:14:0: [sdi] CDB: Read(16) 88 00 00 00 00 00 00 00 00 00 00 00 00 08 00 00 [ 7113.506967] blk_update_request: I/O error, dev sdi, sector 0 [ 7113.508415] sd 0:0:14:0: [sdi] FAILED Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK [ 7113.509330] sd 0:0:14:0: [sdi] CDB: Read(16) 88 00 00 00 00 01 5d 50 a3 00 00 00 00 08 00 00 [ 7113.510252] blk_update_request: I/O error, dev sdi, sector 5860532992 [ 7113.511567] sd 0:0:14:0: [sdi] FAILED Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK [ 7113.512522] sd 0:0:14:0: [sdi] CDB: Read(16) 88 00 00 00 00 01 5d 50 a3 a0 00 00 00 08 00 00 [ 7113.513487] blk_update_request: I/O error, dev sdi, sector 5860533152 [ 7113.515208] sd 0:0:14:0: [sdi] Synchronizing SCSI cache This keeps happening over and over.
