    Hi,

    Does it happen only with video streaming application? You have mentioned –

    “happen sometime overnight while I have 4 video stream going”.

    What exact test application are you running? Can you provide more details on the test environment/setup by providing output of below script- https://gforge.ti.com/gf/download/docmanfileversion/203/3715/gfx_check.sh

    Also can you share the exact steps to reproduce the issue?

    Is the issue seen only with 4 video streams? What is the observation with less than 4?

    Also do you see this message continously ? Please note that its OK to see couple of such messages with an overnight run. It means that SGX lockup was detected at that instance & hence the recovery mechanism was initiated/triggered. As long as it successfully recovers its fine. It should not be a continous message making the system crash or unresponsive.

    Thanks,

    Prathap.
