dmesg with write fault
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:
Distribution is gentoo.

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