Found the cause.
The multipathd which got installed with multipath-tools, which I do not
even recall installing.!!!
I removed the package and it's conf files, AND, just to be safe, I
appended the arg nodmraid
to the linux line in /boot/grub/grub.cfg.
I did it for every menuconfig block.
I rebooted, and all is back to normal.
