Hi John, great, you've found the reason for the problems on MT7621. I'd gladly help with testing (here, also with the cake scheduler enabled where I had these stalls rather frequently). However, two questions: -) Is [1] the patch that fixes the problem? What has been changed there? -) I guess, things apply for 4.9 as well?
Thanks, P.
