- Steps to reproduce
1) Enable Wi-Fi access point
2) Connect a Wi-Fi client to this access point
3) After a few seconds the crash occurs
I'm encountering kernel crashes after updating from OpenWrt SNAPSHOT r16915-bb749e49a6 to OpenWrt SNAPSHOT r16957-3d026d2425. The crash occurs a few seconds after a client is connected to Wi-Fi access point. The crash doesn't occur if Wi-Fi is disabled or if there is no clients connected to AP.
The system stops responding after the crash so I'm not able to provide the full crash log. I can only provide the screenshot of the virtual machine console after the crash which contains the last few lines (see the attached file).
One or more files have been attached.
