Description Matthias Nagel 2016-11-01 08:24:43 UTC
Kernel version: 4.4.26

Graphic card: "ASUS GeForce GTX 660 PCI 3.0 2GB DDR5"

uname: "Linux 4.4.26-gentoo #1 SMP Mon Oct 31 17:05:30 CET 2016 x86_64 Intel(R) Xeon(R) CPU E3-1230 v3 @ 3.30GHz GenuineIntel GNU/Linux

SW versions:
x11-base/xorg-drivers-1.18-r1
x11-base/xorg-server-1.18.4
x11-base/xorg-x11-7.4-r2
kde-plasma/kwin-5.7.5

The system freezes, the X screen gets locked, mouse can still be moved, switching VT console is not possible, three-finger-salute does not work, no keyboard login possible Login via SSH and reboot still possible.

The bug is usually triggered if huge parts of the display needs rapid updates, e.g. compiling a piece of software in a X terminal in full screen mode.

I use the proprietary PGRAPH firmware due to bugs #69882, #93629, #93630 and #95054.

Kernel message:

nouveau 0000:01:00.0: fifo: PBDMA0: 00200000 [METHOD] ch 12 [023f28f000 Compositor[2492]] subc 0 mthd 000c data 00000000

This message floods the logs until they are overwritten from the beginning. The other message is "Missed NN kernel messages".
