Just noted this happened today, running stable/9 ish from august 10th. It looks like I got a good and valid crashdump off of this if anyone is interested. <boot snippet> igb0: <Intel(R) PRO/1000 Network Connection version - 2.3.4> port 0xe880-0xe89f mem 0xfbe60000-0xfbe7ffff,0xfbe40000-0xfbe5ffff,0xfbeb8000-0xfbebbfff irq 32 at device 0.0 on pci5 igb0: Using MSIX interrupts with 5 vectors igb0: Ethernet address: 10:1f:74:2d:08:20 igb0: Bound queue 0 to cpu 0 igb0: Bound queue 1 to cpu 1 igb0: Bound queue 2 to cpu 2 igb0: Bound queue 3 to cpu 3 igb1: <Intel(R) PRO/1000 Network Connection version - 2.3.4> port 0xec00-0xec1f mem 0xfbee0000-0xfbefffff,0xfbec0000-0xfbedffff,0xfbebc000-0xfbebffff irq 42 at device 0.1 on pci5 igb1: Using MSIX interrupts with 5 vectors igb1: Ethernet address: 10:1f:74:2d:08:21 igb1: Bound queue 0 to cpu 4 igb1: Bound queue 1 to cpu 5 igb1: Bound queue 2 to cpu 6 igb1: Bound queue 3 to cpu 7 <panic> GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
