Thanks Dave, I made sure that this patch solved my problem.
OK good, thanks.

I also have no ideas how to solve it, but it seems that it hasn't been a
practical problem yet. So I think your patch is enough for now.
At least with compressed kdumps, the "crash --zero_excluded" command line
option,
or "set zero_excluded on" during runtime, should handle 99% of the cases.
