In fact Anders, I just thought of a potential alternative issue, so do you mind to run a 3rd test?
(c) After running tests (a) and (b) from the last comment, please boot the machine and edit the file "/etc/default/grub.d/kdump-tools.cfg", changing the crashkernel parameter there to be exactly "crashkernel=384M" - after that, please execute "sudo update-grub" and reboot the machine, finally trying a kdump again. With that test, we can be sure it's not a memory issue on kdump environment, since ZFS might consume more memory than kdump boot had reserved.
