For inexplicable reasons, after several other boots to other installations on same PC, 15.4 decided it was OK to boot normally using the originally generated .22 initrd. Felix Miata composed on 2022-05-24 19:42 (UTC-0400):
UEFI booting. pi3p16s154 is nvme0n1p16 ext4 root filesystem LABEL. crypto is not employed anywhere on the PC. 5.14.21-150400.19 kernel boots normally. 5.14.21-150400.22 kernel is not recognizing USB stick insertion, so there's no way I know to get /run/initramfs/rdsosreport.txt onto a stick for susepasting, and susepaste isn't in the emergency shell. Neither does the shell include grep. I rebuilt initrd with add_dracutmodules+=debug but still no susepaste or grep, or lsblk, or fdisk, or improvement.

Is there anything above that suggests why the .22 initrd failed to enable nvme / filesystem to be found?
https://paste.opensuse.org/57952814 is output from lsinitrd /boot/initrd.
I did essentially the same dup to 15.4 a week ago on another PC with same Intel b250 chipset, also UEFI & nvme, and no trouble. I copied each of 3 .22 initrds from the first PC to the second. The first boots normally. The second not, initially stopping at starting dracut initqueue hook, winding up in emergency shell. So did the #3 initrd. The initrd from the update last week copied to today's also fails in same manner.
The big difference between the two PCs: the problem PC contains 2 HDDs with multiple partitions, about half of which comprise several mdraid devices, none of which have anything to do with booting the problem 15.4 installation.
