<pre>Dear nouveau developers and community,
I#m using nouveau on a MacBook Pro mid 2008, with GeForce 8600M GT und Linux
kernel 4.14.90 under NixOS.
After some 30 to 50 minutes of working, the X server always freezes and gives
scattered image. Moving the mouse is often possible, but clicking or typing are
without any effect.
Loging in with ssh is still possible. I also tried to restart the X server, but
it hangs so hard, the only pressing power off button helps.
Here are the nouveau related logs from systemd.
