I upgraded my system from 4.6-RC2 to 4.7-RELEASE and now every ethernet packet I receive crashes the system with fatal trap 12: supervisor read, page not present. This did not happen with 4.6. This is how I know: When I ping another computer, I immediately crash. When another computer pings me, I immediately crash. When I ping localhost, it works as expected, no crash. The following excerpt from dmesg shows that my NIC and graphic card are both assigned irq 11. I am guessing this is the problem. pci1: <ATI model 5144 graphics accelerator> at 0.0 irq 11 vr0: <VIA VT3043 Rhine I 10/100BaseTX> port 0xd800-0xd87f mem 0xef100000-0xef10007f irq 11 at device 16.0 on pci0 miibus0: <MII bus> on vr0 amphy0: <DM9101 10/100 media interface> on miibus0 amphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto Is there any way to influence the irq selection? Can I do this without compiling a kernel? -Ken Jackson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
