ifconfig eth0 down hang issue

Jisha sv

Hi ,

I am using imx6qdl board with 3.10.17 freescale kernel release. I am facing an issue ie. approximate 10 minutes after booting, the system hangs when I execute ifconfig eth0 down. The issue occurs even if I execute the ifconfig eth0 down command soon after booting up and waits for 10 minutes without making the interface up.File system used is Ubuntu 14.04.

Regards,

JIsha

    Jisha,

    I am not familiar with the imx6qdl board.  I need some additional information on the board in order to see how I can help.

    Note that the focus of the Ethernet forum is the DP83xxx and TLK1xx Ethernet portfolio which consists of PHY and MAC+PHY products.  Depending on the nature of your issue, we may need to redirect your post to another forum where you can get help from the right experts.

    Hi,

    We are using a custom board with imx6 solo board.We found this issue in freescale release 3.10.17. Earlier we use kernel version 3.10.9 and this issue is not there. Adding some log info.

    This appears to be a board with Freescale processor and an SMSC PHY.  As the purpose of this forum is support for the Ethernet PHY and MAC+PHY devices from Texas Instruments, I am not sure how I could help.  Have I misunderstood the situation?  If so, could you clarify the tie in for a TI component?
