Failure to start on HPPA

[Matthew Garrett <mjg59@srcf.ucam.org>]

I've successfully booted the most recent nightly build on HPPA, but when
it tries to start the installer I get screenfulls of:

/build/buildd/cdebconf-0.58/src/debconf.c:115 (main): Error reading
configuration information
/build/buildd/cdebconf-0.58/src/debconf-loadtemplate.c:68 (main): Error
reading configuration information

and nothing useful happens. I'm doing this on a serial console, so I
can't easily switch to another VT to see what's going on. Immediately
before this, I had:

Setting up filesystem, please wait ...
umount: /initrd: Invalid argument
