It looks to me like a bus related communication problem (cabling,
termination). But, with -current, it could, of course, also be a problem of
the SCSI sub-system.

-current is pre-1.6, i.e. the area where new development happens. While
this is interesting and exciting, there are times when -current will
puncture your tyres and flood your cellar, so to say. I.e., in -current the
bugs of new implementations are shaken out, so you better know what you're
doing.

1.5 is the most recent release branch, and 1.5.1 ALPHA (which is the
version of my sample kernel) is 1.5 plus bug fixes (most prominently, the
Q700 console panic bug and Quadra SCSI performance fixes).

In a picture:
