It might conversely also be made worse by 6.2 or 6.3. In theory, it
shouldn't, but then again, in theory, I shouldn't have been getting this
problem either.

An update of the OS will have to wait until I can purchase another CF
card to load with OpenBSD 6.3 and migrate the configuration.

Alternatively, if the problem is hardware, I can just replace the whole
box. Updating OpenBSD on the existing one would be a waste of time.

I need a way of ruling out the hardware as being an issue. Until then,
OpenBSD 6.1 stays, unless the debugging facilities in 6.2/6.3 are
drastically different that make troubleshooting this problem easier.

I think I've tracked down the driver source here:
https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/ic/rtl81x9.c
The log suggests it has not changed since the release of OpenBSD 6.1.

I haven't lost my mind...
...it's backed up on a tape somewhere.
