The change made to scsi_da.c in revision 1.28 doesn't quite work right for disks over 2G on 32 bit machines. You can probably revert back to scsi_da.c version 1.27 and fix the problem. Instead of this: (((unsigned long) dp->secsize) * ((unsigned long) dp->sectors)) >> 20ul, The calculation might work better as something like this: (((u_int64_t)dp->secsize) * ((u_int64_t) dp->sectors)) >> 20 That'll probably cause a printf format warning, though.
