connect problems on SMP

[Richard Nyberg <rnyberg@xxxxxxxx>]

I'm having troubles on my SMP machine. Often new connection attempts
just hangs. This makes it almost impossible to e.g. browse the web.
When they don't hang everything works as expected.

The hangs doesn't seem to occur on a UP kernel.

A tcpdump log of a hanging connection attempt is attached.
