Date: Fri, 9 Aug 2013 11:18:51 -0600 From: Bjorn Helgaas <bhelgaas@...gle.com> To: "e1000-devel@...ts.sourceforge.net" <e1000-devel@...ts.sourceforge.net> Cc: "linux-pci@...r.kernel.org" <linux-pci@...r.kernel.org>, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: 3.11-rc4 ixgbevf: endless "Last Request of type 00 to PF Nacked" messages 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-rc4, v3.10, and v3.9, which is as far back as I checked.
