As it stands this openwrt version v19.07.4 still doesnt have this patch

https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=34a96529041d4e9502c490c66f8af0154187c6d2

Added in the latest v19.07 branch - should be in the next stable release v19.07.5

And this patch - https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=c8f8e59816eca49d776562d2d302bf990a87faf0

Helps this situation as well.

LAN & WAN connectivity was lost but wifi worked.

db260179:

@gregoryd Try my https://gitlab.com/db260179/xiaomi-m4a stable branch

Just add your own .config to build for this router, as my changes are specific to the mt7530 and mt76 driver fixes which are generic and might fix your issues.

If it does, i can then try and get them added to the v19.07 branch for future fixes.

[openwrt-bot]

gregd72002:

thanks, I will certainly try it as this issue drives me crazy. It happened again just now

[openwrt-bot]

gregd72002:

@db260179

I dont think this resolves the problem. I've got the problem 2 times in the last 3h.
See dmesg.

[openwrt-bot]

db260179:

Ok so looking at your log, your ethernet is going up and down alot, indicates a few things here.

Bad network cables, poor psu not giving enough power.

Other possibles are an unknown bug for this device, have you tried older v19.07 versions say v19.07.3?

The kernel module crashing is a side effect of some sort of load or connection issue happening.

[openwrt-bot]

figeac888:

@db260179

On my side, I didn't have this issue on v19.07.3.

[openwrt-bot]

gregd72002:

I moved back to 19.07.3 too. So far so good.
@db260179 As for the bad network cable, it was indeed not plugged in properly.

[openwrt-bot]

mrakotiq:

probably same issue like:
https://bugs.openwrt.org/index.php?do=details&task_id=2628

[openwrt-bot]

gregd72002:

A bit of a success - I tried all possible versions v19.07.1 - v19.07.4 and I experienced the issue in all of them daily.

Since, I moved to snapshot (OpenWrt SNAPSHOT r15165-66d12ce667, kernel: 5.4.81), the router has been stable for 5 days so far - longest I can remember

13 Dec: tried also 19.07.5 just out of curiosity - same issue. I'm reverting to snapshot again.

[openwrt-bot]

idoo:

@gregory D where did you get that snapshot? same issue here on 19.07.5

@ivan Verevkin, I compile it myself from the sources

@gregory D Can you share the way to compile it ?

OpenWrt settings target ? options ? etc..

Apocalypse:

@duce I'm also testing my own build from master sources and it seems to be 100% stable. I have not managed to hang it or received kernel panic in the tests that i have done and that gave rise to problems in 19.07 with the old swconfig driver.

I'm compiling latest master sources for all MT7621 targets with luci and some more packages like PPPoE that may be necessary to configure the internet connection. I'm also compiling the sources of all packages to make my own repository and be able to install the packages directly from it. When it's completed i'll post the server url with the builds on the OpenWRT forum.

Hey all,

I build latest code but there are still some issues (related to : https://bugs.openwrt.org/index.php?do=details&task_id=3453) :
Going to monitor it longer.
