Looks like command with similar effect is invoked in script of package itself, executed by `rpm -e' of it. Anyway, did uninstall that `drm-kmp-default'. Tried to hibernate. It worked. Anyway, it is hardly proper to have users re-write that `resume=' parameter of kernel command line. Installer itself ought to create it right, that is, using stable device name from `/dev/disk/by-id' or `by-uuid'. Presumably the same partition as one used for swapping.
