When  I revert back to the older version and update the feed (./scripts/feeds update modemmanager) followed by installing the packages from the feed (./scripts/feeds install -p modemmanager -a) and do a clean openwrt build, I still get the crash. Can you please help provide some direction if you are familiar with this?
