wifi: ath12k: Attempting MLO with main (6.15.rc7) for NCM865 / WCN7850 in station mode leads to crash/backtrace

[Benjamin Eggerstedt]

Dear ath12k-team,

I’ve attempted to use the new firmware (WLAN.HMT.1.1.c5-00284.1-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3) with the latest 6.15.rc7 (main) yesterday and while the module successfully initialises, the system will crash when I attempt a MLO connection.

I could only take a picture (attached) of what was on the screen (including the overloading of characters, this is really how it was) - as there is no trace of this backtrace in “journalctl -k” for the previous boot (as I have to hard reset the system).

I can provide you whatever data you want me to take, just kindly indicate what you need. The setup is readily available to me for the coming days and beginning of the coming week (before I’ll travel for business again).
I used wpa_supplicant v2.11 with CONFIG_802.11BE flag set for compiler. When I get time, I’ll try if v2.12-devel brings any improvements.

Please let me know what you need, will be happy to help where I can!

Thanks,
Regards,
Benny
