booted from USB stick, I have constantly repeating

(ses3:mps0:0:25:0): lost device
(ses3:mps0:0:25:0): removing device entry
ses3 at mps0 bus 0 scbus0 target 25 lun 0
ses3: <LSI CORP SAS2X36 0417> Fixed Enclosure Services SCSI-5 device 
ses3: 600.000MB/s transfers
ses3: Command Queueing enabled
ses3: SCSI-3 SES Device

for different sesN, which are detected many times:
