Comment # 7 on bug 1176465 from Jiri Slaby

OK, I see no suspected changes for your nvme device in the 5.7..v5.8 range. So,
is nvme module in your initrd at all? Could you attach output of:
for a in /boot/initrd*t; do lsinitrd $a; done

If it is in both the old (5.7) and the new (5.8) one, could you try from the
emergency shell:
modprobe nvme
?
