It should, assuming kernel.old is the previous one. Check this out for a bit more details: http://www.freebsd.org/doc/en_US.ISO...g-trouble.html
not much help now , but in the future I would save the kernel originally installed under a name you know means something to you.
Thanks. I actually checked the Handbook before posting here, but missed that bit.
Perhaps you will know the answer to a relate question. The kernel config file I was using didn't boot, so I went back to GENERIC. The modules igb and bce returned compile errors, so I commented them out. However, I don't know what module failed here:
Code:
/usr/src/sys/modules/netgraph/atm/uni/../../../../contrib/ngatm/netnatm/sig/sig_party.c: In function 'uni_sig_party':
/usr/src/sys/modules/netgraph/atm/uni/../../../../contrib/ngatm/netnatm/sig/sig_party.c:916: internal compiler error: in symbol_marked_for_renaming, at tree-into-ssa.c:548
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

I can't find either "netnatm", "netgraph", "atm", or "ngatmin" in GENERIC. Any ideas?
I built a custom kernel on my FreeBSD 8.2-RELEASE server and it failed to boot. I'd like to revert to the previous kernel.
Everytime You want to try a new kernel just type nextboot -k NEWKERNEL. This way if it does not boot, You system will boot the old working kernel on the next boot.

If I simply copy kernel.OK to kernel will this be sufficient?
For the sake of clarity: I have figured out how to reboot the old kernel; now I would like to make the reversion permanent.
This would do:
Code:
cd /boot
mv kernel faulty
mv kernel.OK kernel
Also when building new kernel do it like that:
Code:
# make buildworld kernel KODIR=/boot/NEWONE
This way You will not 'mess' the old one to /boot/kernel.old directory.
... about Your conpilation error, try with this one:
Code:
# make buildworld kernel KODIR=/boot/NEWONE
Sometimes make buildworld is mandatory for make kernel | make buildkernel steps.
