Title:
  10de:0247 [Acer Aspire 9300] Xorg freeze with Nouveau

Status in Accelerated Xorg driver for nVidia cards:
  New
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
  Incomplete

Bug description:
  I'm experiencing random freezes. the system freezes at seemingly random points and leaves me with only a cursor. i can reboot through CTRL+ALT+SysRq REISUB, and it does close open programs properly, though unsaved data is lost. It happened while:
  -using firefox with 5 tabs open, but otherwise idle;
  -using Firefox, scrolling down a long webpage. the scrolling seemed to overflow and firefox greyed out, then system freeze;
  -using LibreOffice, 1 document open, editing a textbox, specifically clicking away from the textbox.

  i did play some youtube videos both full screen and in a tab, but
  didn't notice performance issues. didn't invoke a freeze.

  I'm on Nouveau because of the NVIDIA security patch debacle (bug
