Signals are described in systemd(1). Will look into for howto enable specific udev debugging. Also reattached md2 as a spare for md4. A sync error is shown now. What's odd is that the system now did return to initrd... Captured serial console logs: Couldn't finalize remaining DM devices, MD devices, trying again.
