NVIDIA have released driver 460.67, and details are here:  https://forums.developer.nvidia.com/t/linux-solaris-and-freebsd-driver-460-67-long-lived-branch-release/172742

The details mention ‘5.11 release candidates’ but they probably should have said ‘5.12 release candidates’, as the previous driver worked OK with kernel 5.11, and this new one works OK with 5.12 (tested with 5.12-rc3)

In other news, I should mention that the KVM/USB crash problems I had reported (to the LKML..) were fixed in 5.12-rc3..
