It's interesting that it seems to be broken on freefall right now.
dmesg prints just one line.  But the bug seems to be in printing that
line instead of nothing.  The message bugger is full of syslog messages
do there are no kernel messages to print, but the tail of one of the
syslog messages is printed because its markup has been clobbered by
the buffer wrapping around.
