I am running/testing FreeBSD-CURRENT 7.0 Dated Fri Jul 27. amd64 On boot-up, SCSI disk speed being reported as 1/2 that found when using 6.2. It also seems to be somewhat unstable. FreeBSD 7 da0: Fixed Direct Access SCSI-3 device da0: 160.000MB/s transfers (80.000MHz DT, offset 63, 16 bit) da0: Command Queueing Enabled FreeBSD 6.2 da0: Fixed Direct Access SCSI-3 device da0: 320.000MB/s transfers (160.000MHz DT, offset 63, 16 bit), Tagged Queueing Enabled However the transfer speeds seem to be about the same. I have tried 2 different TYAN S2881 opteron board with built in Adaptec SCSI (ahd - AIC7902 Ultra320) Why would 7.0 be reporting disks at 1/2 speed? Thanks! Nicole
