Failure to boot: init: Unable to create device: /dev/kmsg

Tried to upgrade my testing Linode to new Ubuntu, upgrade did not work correctly (accidentally had something running which should not have been). It then was restarted.

Now can not connect to it all.

Going through Lish I get

console [netcon0] enabled

netconsole: network logging started

drivers/rtc/hctosys.c: unable to open rtc device (rtc0)

md: Waiting for all devices to be available before autodetect

md: If you don't use raid, use raid=noautodetect

random: init urandom read with 75 bits of entropy available

Filesystem check or mount failed.

A maintenance shell will now be started.

CONTROL-D will terminate this shell and continue booting after re-trying

filesystems. Any further errors will be ignored

The key part seems to be

init: Unable to create device: /dev/kmsg

I found this referencing problem with grub configuration resulting in this error:

http://unix.stackexchange.com/questions … ot-failing">http://unix.stackexchange.com/questions/91063/why-is-the-kernel-boot-failing

but since there is no Grub, can not do much with it

Anyone got any ideas?
