Crash dump interpreted output

r315333 seems to have introduced a trap 12 panic on boot on the following hardware:

ix0@pci0:6:0:0: class=0x020000 card=0x00068086 chip=0x10fb8086 rev=0x01 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82599ES 10-Gigabit SFI/SFP+ Network Connection'
    class      = network
    subclass   = ethernet

System is 10.3-STABLE amd65 r315899.

I am attaching core.txt.0 from the panic.

Note that this does not happen on the Intel X540-T1 card which is also an ix0 device.

I rebuilt the kernel (r315918) and the problem seems fixed. Thanks for the quick response!
