FYI, RPi3B: da0 vs. pass0 for same USB media based on initial_turbo=60 in config.txt ?

With initial_turbo=60 in config.txt content used by RPi3B's
I get:

da0 at umass-sim0 bus 0 scbus0 target 0 lun 0
da0: <Samsung PSSD T7 Touch 0> Fixed Direct Access SPC-4 SCSI device
da0: Serial Number ***REPLACED***
da0: 40.000MB/s transfers
da0: 1907729MB (3907029168 512 byte sectors)
da0: quirks=0x2<NO_6_BYTE>

Without initial_turbo=60 being placed to be used by RPi3B's:
(so no initial_turbo assignment was made)

pass0 at umass-sim0 bus 0 scbus0 target 0 lun 0
pass0: <Samsung PSSD T7 Touch 0> Fixed Processor SCSI device
pass0: Serial Number ***REPLACED***
pass0: 40.000MB/s transfers

(The pass0 case does not end up with mount root working:
timeout results. For reference, the Serial Numbers did
match.)


In both cases, those lines are just after the text (diff
of serial console captures used to establish sameness):
