[Bug 1513650] [NEW] Kernel stalls on boot if the nouveau module isn't blacklisted

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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.
