The issue is triggered when doing a continous external power-cut for every
25sec since power ON. After a week or two observed this issue. There is no
additional work load on CPU during the test, it just boots to a lxde desktop.

I did ran similar testes on our downstream kernel 4.4 and 4.9 kernel few weeks
back, observed similar issues.

Didn't check that. How exactly to check whether xattr is used ?
