Well, I don't know where the bug lies, but I doubt it has to do with interr= upt=20 routing. Based on the vmstat -i output, none of the devices on the system= =20 are storming (or even close to storming) so I don't think the routing can b= e=20 at fault here. It does seem that all the reports I see now of problems wit= h=20 interrupts (other than a problem with storm on irq 20 with acpi0 when it is= =20 not shared with any other devices) involve ata(4). =2D-=20 John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =3D http://www.FreeBSD.org
