igb: probe failed with error -2; Intel I354 Ethernet connection with Marvell 88E1512 external PHY

[YAham]

Hi,

We are using Avoton platform in which four Intel Ethernet connections I354 will be present. We using Marvell 88E1512 as external PHY device. We installed windows igb drivers, prowinx64 and Ethernet got working in windows. But if we boot to linux means, we are not able to find any Ethernet connections. If we run command "lshw -class network", it shows as below message (which four controllers are unclaimed.)

And when we try to print "dmesg" command, we are getting related to igb drivers as following lines.

We tried installing igb Standard drivers from Intel for but having same behaviour.

Your help on this will be appreciated.

Hi YounusAhamadShaik,

Thank you for the post. Just to double check if you are using the Supermicros system? Can you check w/ them for customized Linux driver.

Hi Wb,

Thanks for your reply. Please find the configuration we used as below.

SOC : Avoton (Intel Atom C2750 or C2550)

Processor : Edisonville

Memory : 4GB (8 No of 512Mx8) or 8GB (8 No of 1Gx8) on board

SGMII : Two 2.5G direct from SOC

PCIe : Three x4 PCIe ports

SATA : One port, 6Gbps direct from SOC to SATA NAND FLASH

USB : Three USB 2.0 ports

Expansion : M.2 SSD on One PCIe x4 port

As this is not Supermicros system, we are using MicroServer. Please find the datasheet for this system in below link.

Your help would be very much appreciated on this. Do you think, we need to use customized Linux driver for this? Because we are using below latest Intel standard driver.

With proper uninstalling inbuilt igb drivers from Linux and again installing igb drivers (provided link in previous reply), we were able to get the ethernet ports working fine. But if we reboot the system, we are not able to see the Ethernet controller working. But on Linux version 12, we are able to make ethernet working without any issues. I suspect due to inbuilt kernel drivers might be problem for this.

Could anyone please provide some solution for this???

Hi,

After installing drivers and restarting Linux (version 14.04 Ubuntu) drivers gone away. So by running command rmmod igb; modprobe igb, again able to retain igb drivers working fine. Could you provide any input on this strange behaviour?

Thanks and regards,
