Hi,

I appreciate your concern with the issues that you are experiencing,
however, I think you are pointing at the wrong root cause.

This bug is a spurious warning message, that should have no effect on
your system unless you actually have ECC memory and are expecting to
make use of it. It won't make you system unusable.

Yes, there are usability issues with the oops reporting tool, but I
suggest you go ahead an file any oops reports that don't point to this
bug, as they are more likely to be the cause of the issues that you are
experiencing, and so will be much more helpful in trying to determine
what is going on.

Thanks,

James
