Is your host adapter is VIA UHCI?
if so, maybe similar problem with kern/11018.
(i.e. some other ports have had the same problem,
 but I guess gcc4 triggers it on i386 and amd64.)

IIRC, MS Windows also has a patch for VIA UHCI with
some fast AMD CPUs, so I guess there is some timing problem
on VIA's one.
