The error is extremely verbose but basically means the drive didn't
respond to a command in time so the driver gave up and aborted the
command.  There's not enough information to tell why this happened so
perhaps one of the Adaptec people will respond.  My only problems with
ahc(4) were related to either interrupt sharing or placing the card in a
non-bus mastering PCI slot.  It appears your board is on irq 14.  Are you
sure you don't have an ATA controller on board or somewhere that is also
using that irq?
