Not really... I have the same problem, and no one seems to have any
idea what is causing it:-( I traced it to the same place, but the
problem is that you can't really even print anything, (at least not
with my limited knowledge), because of the following in head.S:

/*
 * Use the first pair of BAT registers to map the 1st 16MB
 * of RAM to KERNELBASE.  From this point on we can't safely
 * call OF any more.
 */
 lis	r11,KERNELBASE@h
.
.
.

So, we can't use prom_print to print checkpoints and we can't use
printk yet.
