It typically needs a hard reset after locking up after reducing tags 1-3 from 64. The drive is alone on the SCSI bus and properly terminated. I currently don't have any error messages from when the drive locks up, though the typical sense code is 0x151. relevant dmesg bits: . . . ahc0: rev 0x00 int a irq 11 on pci0.18.0 ahc0: aic7880 Single Channel A, SCSI Id=7, 16/255 SCBs . . . da0: Fixed Direct Access SCSI-2 device da0: 10.000MB/s transfers (10.000MHz, offset 15) da0: 8347MB (17096357 512 byte sectors: 64H 32S/T 8347C) . . . I've put a quick quirk entry for this drive with tags reduced to 32, and so far, haven't had any problems, though I haven't tried any other settings to test performance. - Jason To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
