Hello,
thanks for the quick answer. To answer Ganapathi's question, all I have
to do in order to trigger the issue is to:
1. Upgrade kernel as usual.
2. Reboot and see the wifi going insane.
If I want to get it working properly I have to:
1. Downgrade kernel to 4.12.12.
2. Make sure initramfs and the uImage for u-boot have been generated for
the 4.12.12 kernel again (my distrubution has a script that takes care
of this).
3. Perform a "shutdown now". A simple soft reboot, and even pressing the
reset button on the ESPRESSObin isn't enough to completely reset the
state, if you reboot this way you will get the "fw is already running !"
message and it will not work. You have to unplug and then replug the
board. After that kernel 4.12.12 will boot and wifi will work.
Here is the dmesg output:
