Title:
  Kernel stalls on boot if the nouveau module isn't blacklisted

Status in linux package in Ubuntu:
  Expired

Bug description:
  I bought a ASUS N550JK laptop and that uses Hybrid Graphics (Intel + Nvidia).
  As you boot the installation iso everything is fine until you reboot the first time.
  When you what for the splash to finish loading the kernel to give you X and the login session it just seems to continue working, but nothing happens for a long time. This is caused by a bug in the nouveau driver when it's loaded by the kernel.

  I found a temporary solution to that issue which is to manually edit
  the kernel boot command line and delete splash quiet and then instead
  add this instead:

  modprobe.blacklist=nouveau

  If you then press F10 to boot the kernel the problem disappears.

  I have the same problem with the same computer if I install Mageia 5
  on it so I can't see any other cause than the nouveau driver.

  I have seen the kernel telling me with alot of lines that there's a
  bug in nouveau.

  Description:	Ubuntu 15.10
  Release:	15.10

  linux-image-4.2.0-17-generic

  I expected that you'd at least always be able to get X working when
  you install Ubuntu completely fresh.

  Instead I had to change the kernel boot command line everytime.
