Hello Krystian,
in August you mentioned you could try to bring Sean Wang's mt76 USB fix into
the Ubuntu kernel. The full series has since landed in v7.3-rc1 ("harden USB
reset and disconnect paths": d23353688dd0, 161596f033e8, e137e5fd245c,
7910bd565d8b, a4803d1801c7, b994cb409f21, with the dependency 5323d3e50c20).
I see the same MT7921AU USB hang on resolute (7.0.0-38): the whole chip
(WiFi and Bluetooth) stops answering, with "vendor request ... failed:-110"
every ~3 s, and only a reboot recovers it. Logs are in LP#2167595, comment #16.
Would you consider an SRU of this series for resolute (and noble HWE)?
I can test a PPA or -proposed kernel on affected hardware.
Thank you,
Piotr
