connect problems on SMP

[Matthew Dillon]

: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.

    Ok, I need some additional info... is it incoming or
    outgoing connections that aren't working properly?
