What prior version were you running? I made several small changes between 
NetBSD-4 and NetBSD-5:
    - Added fast scsi support to WD33C93B.
    - Set the appropriate (I'm pretty sure) clock divisor for the scsi chipset.
    - Started using burst dma mode, rather than dma mode.

Could be something else entirely, but if you're interested in building an 
install kernel I could provide a two line patch to effectively revert the above.
