Boot Loader Broken?

[Schiz0]

Hey,

I recently upgraded from 6.3-PRERELEASE to 7.0-PRERELEASE. I had some
problem with the ports, but I got that taken care of.

Now I'm having another very odd problem.

I originally noticed something odd when I tried to shutdown from
multiuser mode into single user mode. I ran "shutdown now" as root in
multiuser. It said it was shutting down, etc. But then, it gave me the
normal multiuser login prompt. So then I tried rebooting completely,
and that's where the big error came up:

-----------------------------------------------------
FreeBSD/i386 bootstrap loader, Revision 1.1
(root at Mercury, Tue Jan 8 14:22:21 EST 2008)
> \
\: unknown command
-
/boot/kernel/kernel text=0x29e868 data=0x2db8c+0x23814
syms=[0x4+0x34c10+0x4+0x43ef1]
Hit [Enter] to boot immediately, or any other key for a command prompt.
Booting [/boot/kernel/kernel] in 4 seconds ...
-----------------------------------------------------

Why it trying to run the command "\" ? Right before I did this, I
rebuilt world, including the kernel. I installed the new kernel, and
was moving down to single user to install world.

Is my bootloader corrupt somehow?

Thanks.
