Yes, we test on 8QXP MEK board with L5.10.72 release reproduce the ISI overwrite issue

both single camera and multi camera cases can reproduced this issue,so we ask FAE and found the errata patch,but now add L5.10.72 patch with multi camera case also have issue

If you are using multiple camera in L5.10 , you need also apply the 0002& 0003 patch in 4.14.98.
