We were finally able to cobble together a system to perform some testing on the 
provided Ubuntu test kernel.
Here is what was tested (using Debian s390-tools 2.14):

- Using zipl to install the bootloader to NVMe works as expected.
- The kernel IPLs and the IPL type is properly identified via lsreipl
- chreipl/reboot to the same NVMe device works as expected.
- chreipl/reboot to a DASD works as expected.

What could not easily be tested in our environment:
- chreipl/reboot from the DASD back to the NVMe device.
- chreipl involving an FCP device.

Though, knowing what has changed in the code, and knowing how reipl
works, I have no reason to suspect that either of these test cases could
cause any issues. I would be confident to give a thumbs up here.
