Do you mean http://www.coreboot.org/Debugging ?? I tried that, but the errors are different everytime and not always in
the
exact place so it is hard to put a finger on it using this method.
Did you try a backtrace in those cases? What did it say?

Here is my GDB dumps they all seem to be related to x86emu but different every time? Do you see anything useful??
