Supply the following if possible:

  • Device problem occurs on
  • Software versions of OpenWrt/LEDE release, packages, etc.
  • Steps to reproduce

I have observed the following on all recent versions of Openwrt 18.06 on X86_64. When I install the kmod-iwlwifi and the appropriate iwlwifi-firmware-iwl7265d I see numerous stack traces in the dmesg log when I load LuCI and the Wifi doesn't appear to work. The hardware in question is an Intel M.2 3165 Wifi card inside a ZBOX Nano CI327.

Stack trace is as follows:
