I have a hardware problem with a disk drive. Last night I received
millions of messages like:

They were going to messages and the console as fast as the system
could log them. ad0 is not the boot disk but is used to hold large
files. I have seen somewhat similar problems once before and
replaced the drive. That was about a year ago. This time I am
suspecting the IDE controller. Is this reasonable, or is it still
likely a drive failure?
Rebooting the system appears to have temporarily terminated the
problem as I am no longer receiving the messages and nothing appears
to have been lost on ad0. However, the bulk of data on it are the
news archive and other archive files that were replaced shortly after
the reboot.
smartctl shows passed on the drive, but I believe I am reading that 6
sectors have been remapped.
