And obviously involves the nvidia (their older 9631 propietary) driver. What
ip_tables is doing here? Maybe the IRQ of the agp and the network card are
being shared?

-rt1 did not have any of these problems.

dmesg has all of them (without the times) if anyone working on this is
interested.

BTW, kernel seems to be working OK otherwize.
