> nvidia: Unknown symbol __x86_return_thunk (err -2) This is boo#1201936 Until fixed packages are available, boot the kernel against which you built the kernel modules, i.e. if you have installed package kernel-default-devel 5.14.21-150400.24.11.1 also boot kernel 5.14.21-150400.24.11.1 (Update kernel) . Seem you have booted 5.14.21-150400.22.1 (GA kernel) instead.
