I can't connect anymore to my home wifi since upgrading my machine from Ubuntu 16.10 to Ubuntu 17.04.
The problem exists with kernel 4.10.0-20-generic from Ubuntu, and remains with kernel 4.11.0-rc6 that I built from linux-wireless. However, I can connect to a wifi network without authentication. In the following logs, beguiled is the SSID of the WPA-protected I can't connect to and FreeWifi the unprotected one for which the connection succeeds. I also copied the firmware files from git://git.marvell.com/mwifiex-firmware.git, without success. Here are the relevant lines from syslog. Network manager complains about a "WRONG_KEY" but obviously I have triple checked the key, simplified it, and checked that I can succcessfully connect to the same network from my Android phone. Let me know if you need anything else to investigate.
