How to fix?

Nobody mentioned this problem back in February when I originally brought
it up (see the hackers thread with Subject: "Latest 2.1R panic. Hmm.")
and got ack's from folks like David Greenman, Gary Palmer, Poul-Henning
Kamp, and Jonathan Bresler as a desirable thing to be able to do.

Thanks,
