Output from dracut showing kernel oops + full system dmesg
When running dracut on my system (Traverse Ten64, NXP LS1088 / aarch64) on Leap

I have tried on two separate systems with two different SSDs:
1) Western Digital WDC CL SN520 SDAPMUW-128G-1022
2) Samsung MZVLB256HBHQ-00000 (also known as PM981a)
Dracut does complete, but the resulting initrd fails hangs at:

(the above repeats constantly, presumably the wrong root device was referenced
in the initrd)
The issue does not occur when the system is booted (as in / on) from a non-NVMe
device (e.g USB), even if there is an NVMe device installed in the system.
