Hi ,

During the kernel booting,it stopped sometimes after showing the message "omap-iommu omap-iommu.1: sys registered".

Please help to solve it. Thank you.

    By the reason it stops sometimes (not everytime), make me think this should be HW issue, and HW design check is needed. Also make sure you are passing enough memory to the linux kernel (mem=256M).

    Hi Pavel,

    I set the mem=1024M.

    Here is the log after the kernel booting.
