Michael,
I enabled DEBUG_LL and EARLY_PRINTK, and found it was an unhandled
alignment trap. I got a few of these:
[ 0.000000] Unhandled fault: alignment exception (0x801) at 0xc06ebeb7
So, I unset ALIGNMENT_TRAP in my config, and am now able to boot.
After a little digging, it looks like something similar to
"EXTRA_CFLAGS=-mno-unaligned-access" might do the trick as well, but I
haven't tested that yet.
It looks like some people have had trouble with this on a CodeSourcery
compiler before [1,2], but I haven't yet found stuff about this on gcc
(I'm using "arm-linux-gnueabi-gcc (Ubuntu/Linaro 4.6.2-14ubuntu2~ppa1)
4.6.2").
Has anyone else had similar issues?
