 Just to add another data point, I have the same problem with a P6-200
 with an Adaptec 2940 controller connected to my drives and a 2940U 
 (ultra scsi) controller connected to my dat drive (HP35480A) and my
 HP 4020i cd-R drive.  The reboots occur when backing up or writing 
 a CD...  I have everything hooked up to the non ultra scsi controller
 now, and it appears to be working fine..  Maybe there is a problem with
 the 2940U support, or maybe when there is a 2940U and regular 2940 in
 the same system???

Does this problem still occur in newer versions of FreeBSD, 
such as 4.3-RELEASE?
