An RPI3 running r331146 reacted more drastically to the insertion of a
USB 3.0 flash drive additional to the one holding /usr and /var; the
console began to emit a flood of gibberish:

which persisted across shutdown -r and momentary power cutoff. Removing pow=
er=20
for a minute or two seems to have restored normal operation. Note the snipp=
ets
of clear text; the serial link isn't the culprit, it's working fine.
The flash drive had been used as swap on a Raspbian system successfully,
and had a vestigal partitioning scheme from a previous FreeBSD-current
installation. However, it wasn't mounted in any way, just plugged in, to
cause the upset seen above. I wanted to try using the flash drive as extra
swap, per advice given elsewhere. Clearly that isn't going to work.
Thanks for reading, and any ideas.
