Running on a newly installed (running for 3+ days) 19.07.3 build and when I looked at the kernel log, found the following:

Disappointing that an official build released just a few weeks ago has this many issues.

As for running the latest master, well I can't sysupgrade to those due to massive changes.
I guess I'll try it on a test unit.

[xyyx]

please use the latest openwrt branch

I have same trouble with latest master branch too

[azuwis]

I have the same problem (eth0: transmit timed out) using latest master (r14267-18fbb9aa21).

It can be easily reproduced by a speedtest, e.g. https://speedtest.net. The problem occurs when uploading, downloading is fine.

A workaround is installing sqm-scripts:

config queue 'wan'
	option qdisc 'fq_codel'
	option qdisc_advanced '0'
	option ingress_ecn 'ECN'
	option egress_ecn 'ECN'
	option qdisc_really_really_advanced '0'
	option itarget 'auto'
	option etarget 'auto'
	option linklayer 'none'
	option interface 'wan'
	option enabled '1'
	option download '0'
	option script 'piece_of_cake.qos'
	option upload '200000'

Maybe changing eth0 qdisc to fq_codel fixes the problem, I did not test it further.

[fluffymadness]

Maybe it helps to narrow down this bug.....
got this on an ubiquity er-x.
This router has no wifi, and it got the internet shared from another router thats connected to the wan port of the er-x.
sqm is disabled, software offloading is disabled, but i have two active vlans on eth port 1 and 2

It seems disabling packet_steering fixes the problem, in /etc/config/network:

config globals 'globals'
	option packet_steering '0'

and reboot, tested on zbt-wg3526-16m r14365-46abcb3ade.

It was enabled by default for mt7621 in https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=dfd62e575c6c39a188a2dbf4aa0c5d1ecf92c57d, which is not included in 19.07.3, odd for this issue.

It seems disabling packet_steering fixes the problem, in /etc/config/network:

Thanks for the tip, after 24hrs, both a 19.07.3 (setting absent) unit and one based on Snapshot r13978-d15b6e4895 (which did have packet_steering explicitly enabled), show no errors.

But then again, it was not always predictable, I had the 19.07.3 unit running for >6 days (as the primary home router) without triggering the issue before I applied this change.

BTW- NBD just committed a roll-back of the enabling of this setting to his staging tree: https://git.openwrt.org/?p=openwrt/staging/nbd.git;a=commit;h=8a1dab11d19525377df8a12ce856e05ef312d76b

So it looks like packet_sterring off is the correct setting for the M76 platform.

[JFtico]

Well, it is back (or still here) in 19.07.9

Even WITH packet_steering set to disabled (as noted above), as that is the default on my builds.

The following error occurred 2hrs after boot, having recently (2 minutes) changed SQM settings (I run SQM all the time), and this happened during or just after a speed test:
