Proxmox VE - issue with 10Gigabit eht card with intelX520

[clared85]

I at all,
I try to use 10Gb card with my zimablade with proxmox VE installed. The card is equipped with intel X520. I can't see the interface with command "ip link"...instead in the output of "lspci -k" I can see this for X520 card:

"...Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFI+ Network Connection (rev 01)
Subsystem: Intel Corporation Ethernet Server Adapter X520-1
Kernel modules: ixgbe
......"

and the output of "dmesg | grep ixgbe":

"ixgbe: Intel (R) 10 Gigabit PCI Express Network Driver
ixgbe: Copyright (c) 1999-2016 Intel Corporation.
ixgbe 0000:01:00.0: Adapter removed
ixgbe 0000:01:00.0: probe with driver ixgbe failed with error -5 "

and so....I can't use my 10Gb card... some can help me?

Tahnks in advance

Hi, -5 typically corresponds to -EIO (I/O error). That suggests the driver attempted to communicate with the device (e.g. via PCI config space, memory-mapped registers, etc.) but something failed at a low level (bus, hardware, MMIO access).

In short: the NIC was discovered by PCI enumeration, but the driver couldn’t initialize it properly.

So this is a hardware related issue, the PCIe / bus-level error is occurring — perhaps a corrected-but-escalated error (AER) or read error when the driver tries to map or access registers — causing the probe to abort with -EIO and label the adapter as “removed”.

You might want to try other slots or BIOS PCIe settings.
