FS#3092 - Xiaomi Router 3G random reboots

Supply the following if possible:
- Device problem occurs on
- Software versions of OpenWrt/LEDE release, packages, etc.
- Steps to reproduce

 

Hello,

I have a Xiaomi 3G router. Since the day I bought it I installed Openwrt and to tell you the truth, with version 18.06 I didn’t have any problem.

A few weeks ago I updated to the new version (19.07) using LuCI and it restarts me randomly.

I tried restoring the router, reinstalling the update and it keeps randomly rebooting. Right now I have it without any additional packages installed and it still keeps rebooting randomly.

I have noticed, that almost every time I see a reboot and look at the log file the first thing that appears is this, that is, the first line after the reboot is:

Please, I need help since I can’t work if it constantly resets. If you need any more information, please do not hesitate to ask me.

I'm sorry, I don't know how to edit my comment. I wanted to remove the default comments and change the tags.

No one? The router keeps randomly rebooting...

Other file...

I can confirm sporadic (rare) restarts of mikrotik rb750gr3 (similar hardware).

Restarts first observed in 18.06.2, then 18.06.4, and now 19.07.3.
I also experience 1 hang of 19.03.3 (need to power off and then on).

From time to time kernel show error "transmit queue 0 timed out" like this and device continue to run without restart:
