And all this time I was beginning to think my card or motherboard was damaged by recent power spikes. I’ve been running memory checkers like crazy!
I have a GTX 1060 3GB (by MSI) card running on a fully patched Fedora 32 (kernel-5.8.15-201.fc32.x86_64). Frequently, but not every time, after Gnome has been locked, a kerneloops “Bug” occurs in the kernel according ABRT, but there is not enough information for a backtrace.
My screen will lock as is (i.e. off or with whatever screen image was on at the time), the keyboard and mouse are no longer responsive at all (I can’t even CTRL-ALT-F4 to switch to a CLI console). CAPS and NUM lock don’t work.
I can ssh into the PC and it’s otherwise fully operational. All server like services are working 100%.
It did it when I was running driver NVIDIA-Linux-x86_64-450.66, so I upgraded to NVIDIA-Linux-x86_64-455.28 and it did it again.
The “BUG” listed in the crash output refers to [nvidia_modeset],
