Using an alpha kernel built from sources from the 21st, I get the
attached messages when I halt my machine. It repeats about 20 times;
I don't know whether it just stopped by itself, or because I pressed
control-C.

Another attempt to boot the machine after this produces something
similar, and then wedges the thing entirely.
