After the update, my igb ports can pass no traffic. If I reboot into kernel.old, they still can't pass any traffic. They won't even work in the PXE ROM. I have to power off, pull the power cables, then boot into kernel.old before they'll work. This behavior is repeatable. $ pciconf -lv ... igb0@pci0:1:0:0: class=0x020000 card=0x34dc8086 chip=0x10a78086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82575EB Gigabit Network Connection' class = network subclass = ethernet igb1@pci0:1:0:1: class=0x020000 card=0x34dc8086 chip=0x10a78086 rev=0x02 hdr=0x00 vendor = 'Intel Corporation' device = '82575EB Gigabit Network Connection' class = network subclass = ethernet ... $ dmesg # on 311787, it's identical whether or not the igb ports are working ... igb0: port 0x2020-0x203f mem 0xb1b20000-0xb1b3ffff,0xb1b44000-0xb1b47fff irq 40 at device 0.0 on pci1 igb0: Using MSIX interrupts with 5 vectors igb0: Ethernet address: 00:1e:67:25:71:bc 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 igb0: netmap queues/slots: TX 4/1024, RX 4/1024 igb1: port 0x2000-0x201f mem 0xb1b00000-0xb1b1ffff,0xb1b40000-0xb1b43fff irq 28 at device 0.1 on pci1 igb1: Using MSIX interrupts with 5 vectors igb1: Ethernet address: 00:1e:67:25:71:bd 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 igb1: netmap queues/slots: TX 4/1024, RX 4/1024 ... $ dmesg # on 312294, when the igb ports are not working ... igb0: port 0x2020-0x203f mem 0xb1b20000-0xb1b3ffff,0xb1b44000-0xb1b47fff irq 40 at device 0.0 on pci1 igb0: attach_pre capping queues at 4 igb0: using 1024 tx descriptors and 1024 rx descriptors igb0: msix_init qsets capped at 4 igb0: pxm cpus: 8 queue msgs: 9 admincnt: 1 igb0: using 4 rx queues 4 tx queues igb0: Using MSIX interrupts with 5 vectors igb0: allocated for 4 tx_queues igb0: allocated for 4 rx_queues igb0: Ethernet address: 00:1e:67:25:71:bc igb0: netmap queues/slots: TX 4/1024, RX 4/1024 igb1: port 0x2000-0x201f mem 0xb1b00000-0xb1b1ffff,0xb1b40000-0xb1b43fff irq 28 at device 0.1 on pci1 igb1: attach_pre capping queues at 4 igb1: using 1024 tx descriptors and 1024 rx descriptors igb1: msix_init qsets capped at 4 igb1: pxm cpus: 8 queue msgs: 9 admincnt: 1 igb1: using 4 rx queues 4 tx queues igb1: Using MSIX interrupts with 5 vectors igb1: allocated for 4 tx_queues igb1: allocated for 4 rx_queues igb1: Ethernet address: 00:1e:67:25:71:bd igb1: netmap queues/slots: TX 4/1024, RX 4/1024 ...
