(In reply to Felix Miata from comment #1) > ToDo: rebuild the RAID TW's > initrds and retest. I tried rebuilding initrds for the RAID installation several times and couldn't get the / filesystem to be found until I chrooted into it and dup'd from 20221008 to 20221205, which rebuilt the latest kernel at least 4 times. First and subsequent boots worked with the the last built whether starting from the ESP on NVME or from original MBR/EXT2 /boot/ filesystem on SATA. Only the first boot failure landed me in a dracut shell. All subsequent to beginning initrd rebuilds simply hung due to unlimited timeout failing to find / on /dev/md3, which turned out to be dracut was excluding 2/3 of the raid lines included in a working initrd.
