We might have some progress here.

After installing kexec-tools_2.0.6-0ubuntu2.1_i386.deb kdump is now loading and the initial reported problem that it was not even able to see the crash memory location is not showing up.

The remaining problem is that the kernel panic is not completing, the VM remaining stuck when the kernel panic is triggered which is a kernel situation. The problem is the same as in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1440103

Going to the initial thread, will you be able to see the changes for kexec that might be causing kdump to not load in the first place?
