Kernel upgrades are completed on the physical hosts and critical machines. They are not done on vps1-vps7, but those machines are all single core and single core machines are not experiencing the CPU stall bugs in 5.16-6.0 kernels.
Some of the other shell servers also are not updated yet but these are sufficiently non-busy that I can easily hit them when nobody is logged in, and for many I have to build kernels yet before I can update. 5.15.71 booted cleanly on all the machines that it is presently installed on.
