I'm working on a Raspberry Pi project that runs headless as a print server. Some features need wi-fi connection, so I added a wi-fi dongle that runs a separate network with fixed IP (wlan1), so users can connect to that network using their phones and configure the local network (wlan0) in a web interface.
Everything was working fine with Raspbian 4.14.79-v7, but when I try to upgrade to a new version, most of the times I get a kernel panic when connecting to wlan1.
Wi-Fi device: Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN Adapter
Steps to reproduce:
- Install Raspbian Lite version 4.19.42-v7 or later;
- Follow these steps: https://www.raspberrypi.org/documentati ... et-sharing;
- Set a network in /etc/wpa_supplicant/wpa_supplicant.conf;
- Try connecting to wlan1: kernel panic most of the time.
I've tested this on a lot of devices (~10), all RPi 3 B or RPi 3 B+, and they all behave like this. Reproducing the same steps listed above, but with Raspbian 4.14.79, they all work as expected.
I've checked https://github.com/raspberrypi/linux for any issues related, but found none.
I'm I missing something? On a clean installation of version 4.14.79, following the steps described at raspberrypi.org, everything works as expected. In 4.19.42 I just get kernel panics.
