I am seeing the same log message from time to time with the result that the network of the router becomes completely unresponsive. Only a reboot helps.

[ajay-sk]

We are working on MT7628 and facing the same issue. Did you get any solution for this issue.

[akent]

Sadly no, we have been forced back to the closed source driver due to this and other problems.

[ajay-sk]

Thanks for quick response and providing the information.

[languitar]

Strangely this doesn't happen in the stable release of openwrt. Only master builds show this for me.

[nbd168]

The stable release can't show this, because it has no support for MT7603 at all.

[ajay-sk]

@nbd168 : Yes, I could only find in the development branch. Do you have any idea of stable Mt76 repo or way to port mtk-wifi-gpl .

[nbd168]

Should be fixed in the latest version
