Hello,

The reason for this verification is that version 1.5.5 of makedumpfile
was tested on kernels up to 4.1 and not later. Fixing that is not just
to trivially change the entry in the file. It requires verification that
makedumpfile will indeed work for newer kernels.

Since the upcoming release of Xenial will introduce a 4.4 kernel in
trusty, it will also become apparent for 4.4 kernels.

I am going to verify if this version limit can be bumped up to 4.4 which
will resolve your problem.

Title:
  makedumpfile generates kernel version error

Bug description:
  == Comment: #7 - Vaishnavi Bhat  - 2016-03-15 06:16:53 ==
  The following warning is generated by makedumpfile 
  * running makedumpfile --dump-dmesg /proc/vmcore /mnt/201602030129/dmesg.201602030129
  The kernel version is not supported.
  The created dumpfile may be incomplete.

  The makedumpfile version on your machine is 
  # makedumpfile -v
  makedumpfile: version 1.5.5 (released on 18 Dec 2013)

  I did a #sudo apt-get source makedumpfile and checked for the sources. 
  In the makedumpfile.h ,  the LATEST_VERSION is set to
  #define OLDEST_VERSION          KERNEL_VERSION(2, 6, 15)/* linux-2.6.15 */
  #define LATEST_VERSION          KERNEL_VERSION(4, 1, 0)/* linux-4.1.0 */
  where as kernel version on the machine is 
  # uname -r
  4.2.0-27-generic

  Hence we see this mismatch and message as "The kernel version is not
  supported."

  We need canonical to change the value of LATEST_VERSION  so that we do
  not see this message.
