Hi All, This morning I upgraded a Dell PowerEdge 2850 from 6.0-RELEASE to 6.1-RELEASE and found that amr(4) no longer detects my Seagate DAT via sa(4). The system has an embedded Dell PERC 4e/Di with two channels. Channel 0 contains two disks in RAID 1 and works fine. Channel 1 has only the DAT at ID 6 but it is no longer detected. Possibly related to this, ses0 also shows up with the 6.0 kernel but not under 6.1. The diffs for amr show that a ton of (excellent) work has been done between 6.0 and 6.1 so I have no idea where to even begin looking for a solution. Any help is most appreciated. Regards, RJ
