After update to kernel 6.6.6 the drive decrypt prompt doesn't work

Do you have an nvidia GPU?

If so how did you update to the new kernel? Using the cli with dnf or using gnome software app?

This seems a common occurrance when a reboot is done too soon after a kernel upgrade happens since it may interfere with building the kernel modules for the nvidia drivers.

The gnome software app does not wait for the module to be properly built before rebooting.

The fix seems to be to manually remove the improperly built module then rebuild it.

  1. sudo dnf remove kmod-nvidia-$(uname -r)
  2. sudo akmods --force
  3. reboot.

Of course if you are not using the nvidia drivers from rpmfusion then this does not apply.
