Hi,
I am using a custom board with imx6 solo with 3.10.17 freescale kernel release. If i give 'ifconfig eth0 down ' ,after 10 minutes(approximate) the system gets hang. The issue is noted when i change the kernel from 3.10.9 to 3.10.17. When we down the interface "Link is Down" message is not coming. Adding some log info:

Hi,
I realise this is an old post but I am now having this issue with the iMX6ULL. We are using an SMSC PHY but the problem remains if I use the Generic PHY driver.
Was a solution for for this issue?
thanks,
simon
It’s most likely that the problem is related to the driver and not the FEC itself.
If you are using the LAN8720 PHY maybe the following thread might help:

Maybe this entry from an external site may also be useful:
