Kernel issues since -22

[Dale Amon]

I have not got a whole lot of information because this happens
so early in the boot. Basically, no kernel since -22 works on
my Lenovo W520. If I were to hazard a guess, I would say it has
to do with some race condition in the systemctl set up. Even
in -22 I often must boot several times before it succeeds, although
the failures in it seem to be different.

Has anyone else reported similar show-stopper issues in
recent kernels?
