dmesg with write fault

Hello,

on my HP NW9440 Laptop with the following GPU:
01:00.0 VGA compatible controller: NVIDIA Corporation G71GLM [Quadro FX 1500M]
(rev a1)
I am getting MMIO write faults always at the same address. I think these write
faults lock up my machine sometimes. I use plasma desktop environment. To
trigger the MMIO write faults I have to just use the machine. I have not found
a pattern to provoke a hard lockup. 

Known good kernel version: none
Known bad kernel versions: 4.19, 5.0, 5.1, 5.2

Relevant software versions:

media-libs/mesa 19.0.8
sys-kernel/gentoo-sources 5.2.9
x11-base/xorg-server 1.20.5
x11-libs/libdrm 2.4.97
x11-drivers/xf86-video-nouveau 1.0.16
kde-plasma 5.15.5
kde-frameworks 5.60.0
qt 5.12.3

Distribution is gentoo.

Greetings

plasma font corruption

I do not know if the font corruption occurring in plasma is related to the
write faults.
