Hi,
I am experiencing a reproducible HWSI bus lockup on the RTL8922AE
(rtw89_8922ae) triggered by the connected AP changing its advertised
bandwidth in a beacon. During the lockup, the radio is unresponsive and the only fix I could find is reconnecting to the network.
The issue occurs on every boot within seconds of association, and also during normal operation whenever the AP re-advertises its
channel width.
I have tested with both the in-tree driver on kernel 6.19 and the
latest out-of-tree driver from morrownr/rtw89 (git HEAD). Both
reproduce the issue identically.
User-visible impact
-------------------
During the HWSI busy window, all network traffic basically stops. Existing TCP connections stall and time-sensitive applications (VoIP, video calls) break. The Wi-Fi/BT coexistence is also disrupted, causing paired Bluetooth devices to disconnect.
The issue reproduces on every association and also during
runtime when the AP periodically re-advertises its bandwidth (sometimes every few minutes), making connectivity unreliable.

Please try to disable power save and ASPM by
1) iw wlan0 set power_save off
2) reference and install https://github.com/lwfinger/rtw89/blob/main/70-rtw89.conf
and then cold reboot.
