The "bad magic" messages persisted over several reboots, so I don't
think a rogue udevd from the install could have been the problem.
Making sure that all remnants of udev-071 had been removed was the
fix.  (As an aside it's worth noting that the udev-071 "make
uninstall" kills udevd, so it's probably wise to install the new
version and reboot ASAP.)

That works OK when booting, the wierd thing was that when shutting
down I was also getting "bad magic" messages which turned out to be
coming from the hotplug init script.  No idea why, but those messages
disappeared as soon as I disabled the script.
