The box I used to build the last kernel is currently off, but it was a
clean checkout of netbsd-5 as of ~ 200903182200Z, which should have had
Greg's changes.  That was my first thought since the system had been
running a netbsd-5 kernel from mid-January, hence I grabbed the latest
sources and installed a new kernel... the problem still happened.

Note that this is a UP machine (single UltraSPARC-IIe @ 548Mhz).

I guess this is additional incentive to polish off those aceride(4)
changes to keep this machine from spewing all the IDE errors in the
first place... Will have to dig them out of my old -current tree
and polish them off a bit ;)
