here is a problem. this problem existed on the may snapshot, and
still exists. it seems to happen during disk intensive activities,
such as the last two log messages below, when i was doing a make
installworld via lp0/nfs, although it also did it several times doing
installworld and makeworld with /usr/src local, and with no ide flags.

Toshiba Portege 660 CDT laptop
