Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/VividS--vg-root does not exist. Dropping to a shell!

The tipping point seems to be at 146M which works. 145M doesn't
