Comment 12 for bug 1597437

Then you are more lucky than I am. My system hangs from time to time with this patched driver - mouse and screen are frozen, only reboot cures that. It happens approximately once a week, and that doesn't suit me because my system should be up 24/7. Nothing can be found in /var/log/syslog, only Xorg log shows some info about "EQ overflowing" [https://nouveau.freedesktop.org/wiki/TroubleShooting/#index5h3]. So it seems that this patch needs proper testing and its stability depends on PC configuration. Good that it helped someone, but that's not my case.
