Well, it seems to be working now, but not necessarily due to this
patch.  I lost two of the four drives on my ATA RAID card (RAID-5) so
lost my entire system :-(.

Rebuilt the box from the 5.0-RELEASE floppies/net then cvsupped to
5.1-CURRENT.  Reinstalled all the stuff like qmail and apache.  I'm
no longer seeing the "unlocked" messages in the logs any longer.

Thanks for all your help!
