New world (8.0), old kernel (7.x)

[dfj]

Looks like I have a similar problem to this thread:
http://forums.freebsd.org/showthread.php?p=58578

Something, not sure what, went wrong with the upgrade. When booted using the new kernel it gives the following message:

Enter full pathname of shell or RETURN for /bin/sh:

When booting to kernel.old, my 7.1 or 7.2 kernel it gives the following error when trying to login at the console:

login: Could not determine audit condition

Most services, but not ssh are up and working. Based on research, it seems like the new world is installed, but the kernel install went wrong. What is the safest way to install the 8.0 kernel? Would copying /kernel from a boot cd work? Or should I use the install cd and choose upgrade?

Unlike the aforementioned post, I did not try downgrading to 7.x.

What happens when you actually hit [enter] here:

Enter full pathname of shell or RETURN for /bin/sh:

and run fsck -y followed by reboot?

Just tried the fsck without any luck. I can't really give more details since the machine is collocated and I have to ask other people to do this for me.

Any other suggestions?

The kernel from the cd should work. You can also try using the tools in /rescue (maybe).

Boot a livefs disc/DVD;
Do a fsck;
Mount the root partition;
Extract the 8.0-RELEASE GENERIC (./install.sh generic) from the kernels directory in disc1 or DVD or the FTP (ftp://ftp.freebsd.org/pub/FreeBSD/releases/i386/8.0-RELEASE/kernels/).
