Re: xl device doesn't work with ACPI enabled under -current and -stable

:Thanks for the fix. Yes, this fixed the problem. I noticed Eirik Nygaard
:reported the same problem on 1/22. Is there any plan to fix this in the
:-current tree?

    Rongsheng, could you do a boot -v and post a copy of you dmesg for
    both the xl-working AND the xl-broken cases ?

    What stands out here is that the interrupt storm is occuring on irq 3.
    It kinda sounds like the XL device is being routed to irq 3 rather then
    to the IRQ it is supposed to be routed to.
