I had a working 3.0 installation, and CVSup'ed to the RELENG_3 stable 3.1.
The make world went fine and with a bit of fiddling with the GENERIC
config file, the kernel re-compilation came off as well.
But apparently the kernel is in the "Wrong format!", or so it says right
after the initial boot: screen.
I am obviously missing something fundamental here. Woulad someone assist
me in discovering what that is?
