Well, I have verified that the 184.108.40.206 kernel compiled with the
CodeSourcery toolchain is not the issue.
I finally found an old rootfs on my system that was originally
built for kernel 220.127.116.11 with the oabi toolchain provided by
Cirrus Logic. That rootfs starts fine until the init process
tries to load a kernel module then it of course dies. But the
other init shells start fine and busybox works on those terminals:
tty1 - on-board LCD controller + USB keyboard
tty2 - on-board LCD controller + USB keyboard
ttyAM0 - UART0 serial port
My boot terminal is actually ttyAM2, that's the one that locks up.
Here's part of the boot messages.

I have been messing around with ext-tool.mk and package/Makefile.in
trying to figure out what is missing/needed to get the external
multilib toolchain to work correctly. Unfortunately I think I'm
way over my head.
Have you had any other ideas on this?
Thanks for all your help,
