I don't remember seeing anything like that, and in reviewing the boot message, I didn't see anything. :) In any case, here's my latest update: # cd /usr/src/sys # cvs update -Pdr RELENG_4 -D'August 5, 2001' [ Build new kernel, install, reboot ] This works fine. So, sometime after August 5 it's broken. I noticed a change on the 6th, so I'll update to the 7th and see what happens.
