A couple of days ago I tried to migrate to FBSD 2.2.7R, by spliting the disk into two slices, putting FBSD on the upper 4G and NT on the lower 4G ('cos NT wont boot from the upper 4G slice). Mostly fine, samba running very smoothly, shlight not so good (kernel smb_receive: smb_error = -31). However, the system keeps falling over with a ncr0: timeout (different ccb value each time), and needs a power cycle to reboot. Usually falling over again during the first fsck attempt, requiring a second power cycle before I can login again. I checked the physical interface between the controller and the drive (and shortened it). I have eliminated shlight as a source of the problem. In the end I had to back out and go back to NT :-( Q1. I'm a bit new to scsi and unix (FreeBSD user since Feb 98): Do you think the problem is the controller, drive or software? Q2. I will be buying 3.0R CDs as soon as they appear over here: Do you think that CAM will significantly improve my situation?
