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. Ciao, -- David N.
