Public bug reported: (Apologies for not using ubuntu-bug, but I've been waiting an hour for it to get past "Collecting problem information".)
I upgraded system to kernel 3.16.0-43.58~14.04.1 (amd64) today. X now crashes with the error "nouveau - gpu lockup" whenever I run Google Chrome (google-chrome-stable 44.0.2403.89-1). Big black boxes appear when I open a bunch of tabs and hover the mouse over the tabs. Eventually X crashes, freezing the whole screen with garbage all over it, and syslog contains the "nouveau" errors below. The problem went away when I downgraded libdrm2 and libdrm-nouveau2 to 2.4.56-1~ubuntu2 (was 2.4.60-2~ubuntu14.04.1). I did this after reading https://bugs.freedesktop.org/show_bug.cgi?id=89842#c19 (see comment #19). Here's syslog. The "nouveau gpu lockup" error doesn't appear, but it did appear onscreen.
