Subject: Re: usb/93640: [ehci] [irq] device ehci causes interrupt storm on this 
MSI amd64 motherboard
Date: Sat, 3 May 2008 15:52:39 +0100

 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.
 
 $FreeBSD: src/sys/dev/usb/ehci_pci.c,v 1.28.2.3 2008/04/23 18:50:19 jhb Exp=

 Thanks, whoever did it, either knowingly or not.
