Thanks Richard,
I traced it down to a symbol being brought in from libc that brought in other symbols that collided with ones on the kernel.
Btw, with your latest changes I have merged them in with the latest 9front and its running on my Pi 1 and Pi 2.
Only weird problem is when I do fshalt -r. My pi2 goes unstable with panics on reboot. Cold reset brings it back to normal.
Does your latest code work on Pi zero? I don't yet have one to test it.
Chris
