There seems to be a problem with later versions of the 2.2-RELENG branch
on specific hardware configurations. There's still not an explenation to
why it happens, nor a complete list of configurations that cause it. The
workaround would be to use either an older 2.2 install disk (like the
one from 2.2.1) or a newer 3.0-current install disk to install 2.2.2.
Once you install it you should be OK (you can then even run
/stand/sysinstall on your 2.2.2 system). When installing with a floppy
from another version, be sure to modify the version in the Options
screen to the one you're actually installing.

Good luck,
Nadav
