console log (X540-AT directly in z420)
I moved the X540-AT card into the z420, so the Magma chassis is not involved (the Magma card is not installed at all). Here's a log of the same failure.

Seems fixed in the 2.10.3 ixgbevf driver from http://sourceforge.net/projects/e1000/files/ixgbevf%20stable/ |
Created attachment 107263 [details] console log (X540-AT in external Magma chassis) When I enable VFs via sysfs on an Intel X540-AT, I see an endless stream of ixgbevf 0000:08:10.2: Last Request of type 03 to PF Nacked messages. This on an HP z420 with the Intel X540-AT in external Magma PCIe expansion chassis. No cable is attached to the X540-AT. ixgbe is built as a module and is auto-loaded during boot, with no VFs enabled. The "Last request Nacked" messages start when I enable VFs with: # echo -n 8 > /sys/bus/pci/devices/0000:08:00.0/sriov_numvfs ixgbe 0000:08:00.0 eth1: SR-IOV enabled with 8 VFs pci 0000:08:10.0: [8086:1515] type 00 class 0x020000 pci 0000:08:10.2: [8086:1515] type 00 class 0x020000 ... ixgbevf: Intel(R) 10 Gigabit PCI Express Virtual Function Network Driver - version 2.7.12-k ... ixgbevf 0000:08:10.2: Last Request of type 03 to PF Nacked ... This happens with v3.11-rc6, v3.11-rc4, v3.10, and v3.9, which is as far back as I checked.
