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.
