sorry that i do not send more information, this not happened again :)
here a part of my dmesg bootup. i use FreeBSd 4.9 on a
HP Vectra VL400. the problem comes up first, as i add the adaptec
SCSI controller, but do not use a disk on it. and i replace both
disks. as you can see the disks are Maxtor discs, and they are new.
i do not change the cable, because it works perfectly before 4.9
from 3.5 to to to to to 4.8.

regards Stefan
