I can't recall, does the cd come with the btx loader? Is it able to see
the hard drive partitions and boot that way?
Did you put anything in loader.conf? I'm guessing that if you're
getting to /boot/loader but not any further, it's something wrong with
the conf file. If you're booting UFS, you might be safe just
deleting/renaming the file.
And just for sanity's sake, you didn't try anything special with geom
did you, such as 4k blocks, geli, etc?

This is a pretty straightforward system, one drive, not large (128GB SSD).
GPT partitioned, gptboot boot code. One UFS root partition to boot from,
a swap partition and, the rest for ZFS.
(At first I tried to do this system with root-on-ZFS but that also failed,
adding "unable to load zpool by guid" or similar before the "can't load
'kernel'" message.)
Once this happens, the disk is unbootable. I can start from the install CD
and access the disk just fine, but even if I move kernel.old back to
kernel, it doesn't boot anymore. Likewise, it doesn't matter if I
overwrite the boot code with gptboot & pmbr from the install CD or the new
ones from /boot after installworld.
The disk looks like:
# gpart show
=> 34 234441581 ada0 GPT (111G)
34 222 1 freebsd-boot (111k)
256 1792 - free - (896k)
2048 8388608 2 freebsd-ufs (4.0G)
8390656 8388608 3 freebsd-swap (4.0G)
16779264 217662351 4 freebsd-zfs (103G)
In the loader:
BTX loader 1.00 BTX version is 1.02
Consoles: internal video/keyboard
BIOS drive C: is disk0
BIOS 621kB/2067924kB available memory
FreeBSD/x86 bootstrap loader, Revision 1.1
(root@builder, Mon Apr 15 09:14:38 UTC 2013)
can't load 'kernel'
Type '?' for a list of commands, 'help' for more detailed help.
OK show

OK lsdev
cd devices:
disk devices:

pxe devices:
OK ls
open '/' failed: no such file or directory
OK help
Verbose help not available, use '?' to list commands
So it's getting the boot device right (disk0p2 / ada0p2), but can't see it
at all.
Does anyone know what might be wrong?
Thanks for any advice!
