I also met this  problem in Linux "rel_imx_4.1.15_2.1.0_ga" downloaded from "linux-imx.git - i.MX Linux Kernel ". It almost  took me one week to find way to fix this problem. And finally, I found the answer in "https://patchwork.kernel.org/patch/9363667/". I wish this could help more people that met the same problem.

[gengde_zheng]

thank you very much.i also met this  problem  and have fixed it as you said.

You may also with to try the following kernel patch:

Google Groups 

I have not tested this change myself, but the issue appears similar re: crash. The errors preceding the crash would likely be a different issue though.

Hi

kernel panic may be caused also hardware issues, please recheck

memory with ddr test

https://community.freescale.com/docs/DOC-105652 

and check usb subsystem with linux unit tests (imx-test../mxc_usb_test)
www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-test-5.7.tar.gz
