I'm just gonna throw this out here for comment because I have no idea
where to look to fix this. Maybe different drivers, maybe a setting
that I'm not aware of, maybe wait for updates. I had none of these
problems with Jessie but I was using the driver from the Nvidia site,
not the Debian package. There's two errors that pop up. A lot. And
with frequent system lock-ups. The log is filled with this nouveau
error, hundreds, in fact. I have not problem going with either the
Nvidia website driver or the Debian package but until I finish about two
weeks worth of work I can't chance another upgrade/meltdown scenario.

This chrome/nouveau occurs with much less frequency, it appears that it
may be concurrent with a webgl failure indicated by a pop up window, it
freezes any input but the mouse pointer moves and the system monitor
graph in the panel keeps moving. Only a hard reset and reboot returns
control.
