Subject: Kernel crash when scanning for APs in huge WiFi environment - Ath10K - ARMV7 - Linux 4.14.73

Hi,
I apologize in advance if I am writing at the wrong place.
We have developed a custom embedded board based on ARMV7. On the board there is a Telit WE866C3-P Wifi module (based on ath10k).
Linux : 4.14.73 (YOCTO/poky)
Microcontroller : SAMA5D27
The board is working perfectly in a normal Wifi environment (e.g., at office).
But when the board is put in a huge Wifi environment (e.g., 350 APs with 2 antennas each with more than 600 visible BSSIDS) the Linux kernel crashes when attempting to connect to a Wifi network using wpa_supplicant.
When the Wifi antenna is attenuated with some electromagnetic obstacle (e.g., hand or metallic shield), the board connects without any problem.
The problem is the same when running a scan from wpa_cli .
Do you have any idea where I can find some clue to resolve this issue?
Many thanks in advance !
VinceCube
