Summary - Comtrend VR-3026e kernel panic using last snapshots
Task Type - Bug Report
Category - Kernel
Status - Unconfirmed
Assigned To -
Operating System - All
Severity - Critical
Priority - Very Low
Reported Version - Trunk
Due in Version - Undecided
Due Date - Undecided
Details - Supply the following if possible:
- Device problem occurs on
- Software versions of LEDE release, packages, etc.
- Steps to reproduce
Problem occurs on Comtrend VR-3026e with last generic snapshots
Symptoms/How to reproduce:
1. Using CFE bootloader in "Update Software" mode try to flash any generic or smp snapshot of LEDE (of course for this board so file lede-brcm63xx-generic-VR-3026e-squashfs-cfe.bin)
2. After flash, turn up the router, and after while ~10sec it crashes and reboots
Backstory:
I need newest snapshot for my project and I am pretty sure that on the same device snapshots from around April-May/2017 worked (sadly I don't know exactly which).
Just mention that last snapshot of OpenWRT works:

I have access to serial console now and this is complete log from starting from flashing and ending with kernel panic:
