[opensuse-kernel] what does "rerouted to legacy IRQ" mean and how do I prevent it?

I'm having a few odd issues with 12.1+updates on an HP ML570G3 box. I'm pretty certain it's irq related - in 12.1 (kernel 3.1.9-1.4) the irqs for the two storage controllers and the two GigE NICs are "rerouted to legacy IRQs". In 11.4 this does not happen - what does this rerouting mean and is there a way of preventing it in 12.1? thanks -- Per Jessen, Zürich (13.6°C) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
