You'll probably need to experiment. Start with something like 5. If that
works, try cutting it down.

I'll try to get a test-rpm with the patch I sent earlier built
soonish, so you can try that.

I don't think udevsettle would help things anyway.  It looks like your
devices may have come online before udev was started. In that case, udev
won't handle them, which is why the multipath call exists in rc.sysinit.
