Subject: Re: usb/93640: [ehci] [irq] device ehci causes interrupt storm on this MSI amd64 motherboard

This problem is gone in RELENG_7 as of 2008-05-03. Interrupt count is
now very low and normal, the machine is usable with device ehci.
There has been a recent change in ehci_pci.c which might explain it,
but I don't know what has been changed.
