After a lot of boot attempts I have the following picture: 1. It always mounts fine when verbose message is selected. 2. It mounts fine when the line below about 'umass0:1:0: Attached to ... ' is printed, if it is not, the mount fails later after 20 secs waiting; here is a working boot: ... uhub1: 2 ports with 2 removable, self powered uhub0: 13 ports with 13 removable, self powered ugen0.2: <SunplusIT Inc HD WebCam> at usbus0 ugen0.3: <vendor 0x0489 product 0xe056> at usbus0 ugen0.4: <Western Digital Elements SE 25FE> at usbus0 umass0 on uhub0 umass0: <Western Digital Elements SE 25FE, class 0/0, rev 2.10/10.21, addr 3> on usbus0 umass0: SCSI over Bulk-Only; quirks = 0x8000 umass0:1:0: Attached to scbus1 ada0 at ahcich0 bus 0 scbus0 target 0 lun 0 ada0: <TS256GMTS400 N1126I> ACS-2 ATA SATA 3.x device ada0: Serial Number C196530955 ada0: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 1024bytes) ada0: Command Queueing enabled ada0: 244198MB (500118192 512 byte sectors) GEOM: new disk ada0 pass0 at ahcich0 bus 0 scbus0 target 0 lun 0 pass0: <TS256GMTS400 N1126I> ACS-2 ATA SATA 3.x device pass0: Serial Number C196530955 pass0: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 1024bytes) pass0: Command Queueing enabled pass1 at umass-sim0 bus 0 scbus1 target 0 lun 0 pass1: <WD Elements SE 25FE 1021> Fixed Direct Access SPC-4 SCSI device pass1: Serial Number 575854314134383033483150 pass1: 40.000MB/s transfers pass2 at umass-sim0 bus 0 scbus1 target 0 lun 1 da0 at umass-sim0 bus 0 scbus1 target 0 lun 0 da0: <WD Elements SE 25FE 1021> Fixed Direct Access SPC-4 SCSI device da0: Serial Number 575854314134383033483150 da0: 40.000MB/s transfers da0: 953837MB (1953458176 512 byte sectors) da0: quirks=0x2<NO_6_BYTE> pass2: <WD SES Device 1021> Fixed Enclosure Services SPC-4 SCSI device pass2: Serial Number 575854314134383033483150 pass2: 40.000MB/s transfers ses0 at umass-sim0 bus 0 scbus1 target 0 lun 1 ses0: <WD SES Device 1021> Fixed Enclosure Services SPC-4 SCSI device ses0: Serial Number 575854314134383033483150 ses0: 40.000MB/s transfers ses0: SCSI-3 ENC Device GEOM: new disk da0 da0: Delete methods: <UNMAP(*),ZERO> WARNING: WITNESS option enabled, expect reduced performance.
