Thanks. Since it's a memory corruption (or seems to be) however, it's
possible that the bisection will mislead you. IE. The culprit could be
somewhere else, and the commit you'll find via bisection just happens to
move things around in the kernel in such a way that the corruption hits
that code path instead of another rarely used one.
I would suggest using printk to print out the content of memory where
the code appears to have been smashed at different stages during boot
(maybe even in the initcalls loop in init/main.c) to try to point out
what appears to be causing the corruption.
Cheers,
Ben.
