Hello After testing upstart with serial console i have several results. When booting with added kernel parameters console=tty0 and console=ttyS0,38400n1 the boot process fals to initramfs. After activating lvm volumes with vgchange -ay and exiting shell boot process continues. When booting without this parameters and serial console the boot stops.
It looks like theres a problem with console handling code when booting with upstart and lvm volumes. Thank You ewew
