Hello, After a Debian 11 update, new header was installed : 5.10.0-24-amd64, and after upgrading rtw89 firmware, the driver was not recognized by the system. Dmesg error : rtw89core: loading out-of-tree module taints kernel. rtw89_8852ae 0000:09:00.0: not mfw format rtw89_8852ae 0000:09:00.0: failed to recognize firmware elements rtw89_8852ae 0000:09:00.0: failed to setup chip information rtw89_8852ae: probe of 0000:09:00.0 failed with error -22 I have installed the firmware-realtek package too. Do you have any idea about the problem ? I can't use wifi for the moment. Thank you for your help. PS : I've created an issue into your Github project https://github.com/lwfinger/rtw89/issues/266 Regards, Emmanuel
