Hi,

Please could you use attached patch? This gets rid of the problem by switching to
devd as backend.

It is based on a patch from FreeBSD, with some fixes of mine. Their plan is to have
it merged in X upstream in the near future (I've already submitted my fixes to them
and I expect they will be included as well).

Thanks
