Oh, wait a minute.. that's not the correct IRQ, is it?
Your ueagle-atm must be on this one:
20: 90833792 3057782 IO-APIC-fasteoi ohci_hcd:usb1
In which case, it's not likely to be an interrupt sharing issue. Can you confirm this?
Also, try moving your ueagle-atm to one of the ehci usb ports and see how that affects things. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
