    is there any way to check whether it is due to HW or SW problem.

    from log:

    Unable to handle kernel paging request at virtual address 84aa5390

    Unable to handle kernel paging request at virtual address 9cb018b4

    Unable to handle kernel paging request at virtual address 9caee264

    Unable to handle kernel paging request at virtual address 9caee028

    Kernel panic - not syncing: Fatal exception in interrupt

    like this it is repeating...
