[-- Attachment #1 --] I'm trying to do a dump|restore from one disk to a replacement, with the new disk in a USB enclosure. Every few minutes (though it's random), the writes stop for a few minutes for no obvious reason. I managed to capture one instance with usbdump: 07:34:26.142023 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=16384,IVAL=0 07:34:26.143096 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:34:26.143110 usbus4.2 SUBM-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=0,IVAL=0 07:34:26.143220 usbus4.2 DONE-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=16,IVAL=0,ERR=0 07:34:26.143321 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=32,IVAL=0 07:34:26.143478 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:34:26.143582 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=65536,IVAL=0 07:34:26.145743 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:34:26.145761 usbus4.2 SUBM-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=0,IVAL=0 07:34:26.145842 usbus4.2 DONE-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=16,IVAL=0,ERR=0 07:34:26.145884 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=32,IVAL=0 07:34:26.145964 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:34:26.146027 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=32768,IVAL=0 07:34:26.147098 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:34:26.147114 usbus4.2 SUBM-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=0,IVAL=0 07:34:26.147222 usbus4.2 DONE-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=16,IVAL=0,ERR=0 07:34:26.147299 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=32,IVAL=0 07:34:26.147358 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:34:26.147420 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=20480,IVAL=0 07:35:29.624720 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=0,SLEN=0,IVAL=0,ERR=TIMEOUT 07:35:29.624742 usbus4.2 SUBM-CTRL-EP=00000000,SPD=HIGH,NFR=1,SLEN=8,IVAL=0 07:35:29.624842 usbus4.2 DONE-CTRL-EP=00000000,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:35:29.624858 usbus4.2 SUBM-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=0,IVAL=0 07:35:29.624955 usbus4.2 DONE-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=16,IVAL=0,ERR=0 07:35:29.625051 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=32,IVAL=0 07:35:29.625205 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:35:29.625239 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=4096,IVAL=0 07:35:29.625453 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:35:29.625463 usbus4.2 SUBM-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=0,IVAL=0 07:35:29.625579 usbus4.2 DONE-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=16,IVAL=0,ERR=0 07:35:29.625657 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=32,IVAL=0 07:35:29.625712 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:35:29.625736 usbus4.2 SUBM-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=4096,IVAL=0 07:35:29.625955 usbus4.2 DONE-BULK-EP=00000002,SPD=HIGH,NFR=1,SLEN=0,IVAL=0,ERR=0 07:35:29.625965 usbus4.2 SUBM-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=0,IVAL=0 07:35:29.626078 usbus4.2 DONE-BULK-EP=00000081,SPD=HIGH,NFR=1,SLEN=16,IVAL=0,ERR=0 One anomoly is that the above doesn't match the usbdump man page. The system is a JW-D2500-GT motherboard (Intel D2500 CPU) using the builtin N10 for USB, running FreeBSD 9.2R/amd64. The disk is a new WDC WD5000BPKT plugged into a Sunplus Technology Inc. adapter. I'm not using any hubs. The problem doesn't seem to occur if I just do sequential writes (dd to the disk). Any suggestions? -- Peter Jeremy [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.21 (FreeBSD) iKYEARECAGYFAlKH4QBfFIAAAAAALgAoaXNzdWVyLWZwckBub3RhdGlvbnMub3Bl bnBncC5maWZ0aGhvcnNlbWFuLm5ldDBCRjc3QTcyNTg5NEVCRTY0RjREN0VFRUZF OEE0N0JGRjAwRkI4ODcACgkQ/opHv/APuIdoSwCgt5qzJkl4GipN432QHxGr5hbM WS0An0dbCtZNyaQ5wrHMV4XmWKQ8fSWr =U2AR -----END PGP SIGNATURE-----
