   Installation on another box, also with 5.4R, went well. So it must be
   this particular Dell PowerEdge 750. After moving the disk back,

   % sudo newfs /dev/ad3s1d
   newfs: /dev/ad3s1d: failed to open disk for writing
   % sudo mount /dev/ad3s1d /mnt/a
   mount: /dev/ad3s1d: Operation not permitted

   But dmesg gives right info so not likely the bios.
   Timecounters tick every 10.000 msec

   ad3: 286168MB <ST3300831AS/3.02> [581421/16/63] at ata1-slave SATA150
   Mounting root from ufs:/dev/ad2s1a
