But the post-Linux problem still remains: my BDI has gone for a replacement, so I have to use some early putchars with the UART that was initialized by u-boot. I place two putchars in early_init in arch/ppc/kernel/setup.c, but I just see one. So does that mean my stack's getting corrupted?
Probably your second putchar is after the MMU has been turned on and it the cause for the crash. Remove this code, and use post-morthem dumps of the logbuf buffer. See the FAQ section in the DULG.
I meant 'I've put two putchars one after the other'. I see the first char printed, but not the second. That's what's making me doubt the stack.
About the log buffer: nothing in them. I'll probably have to initialize it 'earlier' in early_init and then figure out something.
