I see that makedumpfile-1.3.8 was recently released, but it still
has a LATEST_VERSION of 2.6.36:

  #define OLDEST_VERSION          KERNEL_VERSION(2, 6, 15)/* linux-2.6.15 */
  #define LATEST_VERSION          KERNEL_VERSION(2, 6, 36)/* linux-2.6.36 */

You haven't stated what your kernel version is, but it seems makedumpfile
cannot get past this point.  On the other hand, the compressed kdump was
created, so I'm not entirely clear.

I don't believe so...

But I'm not the makedumpfile maintainer, so I'd prefer not to give any
definitive answers to your questions.  I've cc'd the upstream maintainer
of makedumpfile.

Thanks,
