The Arris Surfboard SB6190 is listed as affected in that article. PUMA6 has a network packet processor in it. I doubt the problem is with the Atom processor itself. Flows are offloaded onto the packet processor and most of the packets are never seen by the host CPU in normal operation. -- Mikael Abrahamsson email: swmike@swm.pp.se
