Kernel panic after turning on hotspot

After upgrading kernel to 5.14, my laptop encountered kernel panic when I tried to turn on hotspot. When using kernel 5.13 or before it’s good, but I have no backup and old kernel was deleted by package manager.
Actually it’s not immediately panic when I turned on hotspot, but for a period of time----sometimes several minutes, sometimes many hours.

I tried to enable Kdump and found that command “irq/140-iwlwifi” caused this. And my wifi device should be this :“Intel Corporation Cannon Point-LP CNVi”.
