The issue is not yet fixed in our package, but if you had the udev
rule in place and rebuild the initramfs then check if the udev was
included in the initramfs (check with lsinitramfs) and check the
values for the sysctl accordingly.

That said, I'm confident we will see fixes as well inthe corresponding
stable series once in mainline.
