This is my diff:

I just did another 5 boots and this patch indeed seems to fully fix the
problem in my case.

If this does not work for you, maybe you need a longer delay? If you
boot from CD-ROM, then eudev (or other background processes) requiring
some random seeks during startup may easily exceed 1s.

Does manually running 'udevadm trigger --action=add' after startup
mitigate the problem in your case?
