I've noticed that when running the latest forcedeth on an older base kernel (2.6.18 in my case) that enable_irq and disable_irq don't quite behave the same way with using MSI as they do with INTx. 2.6.24 works great on the same hardware so something has changed between at leat 2.6.18 and now to make life better. I've been meaning to look at those calls and figure out if we can replace them with simple calls to disable the hardware IRQs only, but haven't had a chance yet. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
