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-------------------------------------------------------------- cd /usr/obj/usr/src/sys/CORVUS; MAKEOBJDIRPREFIX=/usr/obj MACHINE_ARCH=i386 MACHINE=i386 CPUTYPE=pentium4 GROFF_BIN_PATH=/usr/obj/usr/src/tmp/legacy/usr/bin GROFF_FONT_PATH=/usr/obj/usr/src/tmp/legacy/usr/share/groff_font GROFF_TMAC_PATH=/usr/obj/usr/src/tmp/legacy/usr/share/tmac _SHLIBDIRPREFIX=/usr/obj/usr/src/tmp INSTALL="sh /usr/src/tools/install.sh" PATH=/usr/obj/usr/src/tmp/legacy/usr/sbin:/usr/obj/usr/src/tmp/legacy/usr/bin:/usr/obj/usr/src/tmp/legacy/usr/games:/usr/obj/usr/src/tmp/usr/sbin:/usr/obj/usr/src/tmp/usr/bin:/usr/obj/usr/src/tmp/usr/games:/sbin:/bin:/usr/sbin:/usr/bin /usr/obj/usr/src/make.i386/make KERNEL=kernel depend -DNO_MODULES_OBJ make: don't know how to make /usr/src/sys/sys/_sx.h. Stop *** Error code 2 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.
