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:
