downgrade freebsd 6.3 to 6.2?

[Marko Kobal]

Hi,

I'm having some issues after upgrading from 6.2 to 6.3 (with the mpt driver). I have upgraded both world and kernel and have already done installkernel and installworld and rebooted several times. Now I wish to downgrade to 6.2; I did "*default  tag=RELENG_6_2" in CVSUP file and "make update", but then when I try to run:

/usr/src# make buildkernel

I get:

--------------------------------------------------------------
>>> stage 3.1: making dependencies

make: don't know how to make /usr/src/sys/sys/_sx.h. Stop

Stop in /usr/src.
*** Error code 1

Stop in /usr/src.

Does this mean I can not downgrade back to 6.2!?

Kind regards, Marko.
