ksymoops 2.4.9 can decode variable length instructions before eip
without affecting the reliabiloity of the code from eip onwards. It is
up to the kernel whether it dumps before eip or not.

Nothing I can do about that. ksymoops uses objdump to decode the
instructions and objdump does not know that the kernel abuses ud2a to
add embedded line and file numbers. In any case it is irrelevant, the
only thing that ud2a ever tells you is "here there be BUG()". For
BUG() the code before eip is much more useful, see above.
