Hangs down/up Intel NIC during creating vlan. Bug em driver ???

[Jack Vogel]

Custom kernel, well, does it happen on the installed GENERIC kernel, and
what is needed
to reproduce this, just down/up the interface? And are you saying that it
will happen on
either the 82573 or the 82546 or just one of them??

Would be nice if this stuff could be discovered earlier :( In any case I
will look into it, there
is another reported problems with em and vlans as well.
