[Bug 818177] Re: boot failures caused by udev race

[Dave Walker]

@James, How did you get on with the debug version of udevd?  When we
tried to do the same, we were unable to reproduce the bug, as the debug
statements seemed to slow down udev, hiding the race.  Was this the same
behaviour you encountered?

Thanks.

Bug description:
  After running a do-release-upgrade -d on a natty server, I'm unable to
  boot the machine properly.

  It looks like it doesn't see the local disks anymore.

  I think this looks quite a lot like the debbug linked from here:
