GPU issues
I went to use a couple of the Nvidia GPU machines and found that the GPU was missing in BOINC. This is caused by the "GPL Condom" code added to the 5.9 Linux kernel. It blocks drivers that use both GPL and proprietary symbols. All of my Nvidia GPU machines were on the 5.9.6 kernel.

The display part works fine, its the CUDA and OpenCL capabilities that are blocked, which means I can't use the GPUs for compute work. To work around this I ended up down-grading two of the machines to the 4.19 kernel that Debian buster is currently running. While its easy to select an earlier kernel on the Grub boot menu, its another thing to remove the newer kernel(s) from the machine without reinstalling and that took a bit of experimenting.
