errno 38 is ENOSYS, that means your kernel doesn't have kprobe support in it. All of the dynamic fixes for i915 lid switch and nouveau interrupt de-registration require kprobe support. Try: # egrep 'KPROBE|KRETPROBE' /boot/config-`uname -r` I get this on my system: CONFIG_KPROBES=y CONFIG_KRETPROBES=y CONFIG_HAVE_KPROBES=y CONFIG_HAVE_KRETPROBES=y # CONFIG_KPROBES_SANITY_TEST is not set CONFIG_KPROBE_EVENT=y If you still have the previous kernel installed, try grepping the same from it's config file. If it's been removed, file bugs with your distro.
