Ethernet ping issue

I am using i.MX6 based custom SOM module with ksz9031 Ethernet phy. Linux kernel being used is 3.0.35.

When I do ping test using below procedure, ping fails randomly.

  1. Boot the board
  2. Ping the host machine.
  3. poweroff and reboot the board.

Ping fails to receive the packets with 100% packet loss. To reproduce the issue sometimes I need to reboot the board even for 1000 times. 

It seems like link is going down while pinging. 


What might be causing problem to link to go down? Might this be because of phy skew settings?


Thanks and Regards,
