@ken-vandine, thanks for the log, but I need more traces to determine the nature of the error. Please change /etc/init/ofono.override adding environment variables and "-d" to ofonod exec line:
<< ... env OFONO_RIL_NUM_SIM_SLOTS=1 env OFONO_RIL_TRACE="" env OFONO_RIL_HEX_TRACE="" exec ofonod -d -P stktest,provision,sap,udev,dun,smart,hfp >> Then re-start ofono (on krillin: "restart ofono OFONO_RIL_DEVICE=mtk OFONO_RIL_NUM_SIM_SLOTS=2"). In one terminal, execute: $ sudo /system/bin/logcat -b radio > /tmp/radio.txt And call the ofono script to change call waiting in another console. When it fails, please collect syslog and radio.txt and send those to me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1455574 Title: Failures to disable call waiting To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1455574/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
