Hi,
with the changes (especially for scanning--rtw88) and all the other
minor details gone in the last days I would love to ask people to test
as much as they can on main before I'll merge to stable/14 and also
given stable/15 is imminent.
Unfortunately rtw88 now ( CURRENT revision d3462294c1f0 ) can't
associate with access points while It was working in 659962f96a15 (

This is like net80211 battling against itself. Starts a connection and
then (likely wpa_supplicant) triggers a new one and the previous one
gets abandoned. It's the very old problem which kept iwlwifi from
working so long (along with the fact that we have to unlock/re-lock).
Can you check wpa_supplicant logging what it says? Authentication timed
out?
Sep 5 08:41:41 kernel: [95] rtw880: lkpi_stop_hw_scan: failed to cancel scan:
35 (0xfffffe011439f240, 0xfffffe01155d0f00)
What wonders me a lot more is this.
