            Bug ID: 109397
           Summary: PGRAPH TLB flush idle timeout fail: X hangs, ssh login
                    possible
           Product: Mesa
           Version: unspecified
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/nouveau
          Assignee: nouveau at lists.freedesktop.org

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.
