Title:
  Suspected Race Condition on boot

Status in linux package in Ubuntu:
  Invalid

Bug description:
  Ubuntu Vivid using stock install, no additional configs, on a dual
  boot (Ubuntu + Win7)

  When booting, my laptop will sometimes boot successfully, sometimes
  not, and sometimes, will reboot. Using CTRL+ALT+F1 to get to terminal
  shows me a console flood for Nouveau (sometimes) and sometimes not.
  Sometimes I see messages about firmware not being used/installed.

  I cannot reliably replicate this problem, but I have had similar
  problems running Fedora on this machine with similar console floods,
  which points further up to the upstream kernel.

  I suspect it is a race condition, as if I can see the console flood,
  the laptop often boots successfully, but if I don't I either get a
  kernel panic or a self-reboot.

  Can provide more information/HW details if needed (but not at the machine right now)
