The fs on hd0,1 is xfs. I just did an fsck on it and the fs itself is
fine.

Since it's hard to paste a good amount of code that happens at boot,
here's what I get when running grub-emu from the console with the above
commands. I'll do a reboot later and verify that I get the same errors.
If I see anything different on a regular boot I'll send in a follow-up
email.

One thing that might be potentially useful, when just doing the ls
without the debug=all, I actually get a little bit of output prior to
the out of partition error. In this particular case the output is:

grub> ls (hd0,1)/boot
?^^ ?^^ ^Q^_                                                                   
                                                                               
           error: out of partition
grub>

Not sure what those extra characters are about, but they are consistent
across multiple runs of grub-emu.

So, running ls after setting debug=all I get:

grub> ls (hd0,1)/boot

repeating a few hundred times. There's some other scattered output but
it's very hard to make out. I do see some lines about detecting and
opening the xfs filesystem early in the log.

I have a screenlog of running grub-emu inside a screen session, but I'm
having a hell of a time trying to view it since there are lots and lots
of terminal control characters in it. In case you have a good way to
view it to see the full output, I've attached it. (screenlog.0.gz)

Let me know if I can provide more info.
