Nouveau lockup with Nvidia and Chrome

[John Lyons]

Regular lockups under graphics load.
Existed since 2013 under previous versions of Ubuntu.

Tends to happen when page scrolling or moving quickly through a browser page.
Graphics load related?

Several previous bugs of a similar nature either considered invalid or abandoned due to being on older versions of kernel or Ubuntu.

Log shows.

Sorry to add to my own post.

My Kernel has had boot param set to nouveau.nofbaccel=1

Based on 711434 I am adding nouveau.noaccel=1
Will report back in 24 hours.

 nouveau.noaccel=1 does seem to be the workaround for lockup bugs in nouveau with Nvidia graphics cards. 24 hours stable.

As this is a regular repeatable issue on my setup, if any developer would like more detailed logging please ask.
