FS#1550 - Unable to handle kernel paging request causes router to reboot

- Device problem occurs on
Xiaomi mi router 3G (R3G)

- Software versions of OpenWrt/LEDE release, packages, etc.
Latest trunk (r6893-bfbdeeb) custom build

- Steps to reproduce
Did not notice there is a pattern here.

- The issue
The kernel crash causes the router to reboot. Here are two traces I was able to catch
