Er, and now bizarrely I find that disabling CONFIG_DEBUG_MUTEXES means
it boots, which just seems wrong.
This means I now have an E3 that will boot (albeit slowly) without
having to be fed anything over the serial port. I'll try and get a
tarball of bits and instructions together this week so some other brave
soul can try and let us know if it works for them too. :)
What's everyone else working on at present and how's it going?
