    Hi, i have a segmentation fault with my conduit AEP (MTCDT-246A, Firmware 5.2.1) . my problem happens one time out of ten at the daily reboot, I’m forced to unplug the power supply and plug it back in for it to work again, but the problem comes back from time to time.
    Someone can help me ?

    Hello Anthony,

    Please file a Support Portal Case at https://support.multitech.com/support/login.html. This is either some kind of timing problem in kernel module initialization of mts-io or a hardware issue. Either way, more investigation is needed.

    Thank You,

    Jeff
