[Bug 802626] Re: boot hangs at initrd

[Steve Langasek]

Eduard, thank you very much for your detailed analysis of this issue!
It appears that this may be the same problem as bug #818177 which we're
working on fixing for Ubuntu 11.10.

A wait there is insufficient because another vgchange may be issued
*after* that script ends.  We need to make sure that when udev
terminates, it doesn't leave vgchange hanging.

  boot hangs at initrd

Bug description:
  The system is now unable to boot.
