I have the same problem(using Xperia XA2 H3113), tried the temporary solution but does not seem to work:
I have killed the ofonod process and it does not run anymore but It hangs when I try to start it back:
[root@XperiaXA2 nemo]# pgrep ofonod
[root@XperiaXA2 nemo]# /usr/sbin/ofonod -n --nobacktrace --noplugin=,he910,dun_gw_bluez5,hfp_bluez5,cdma_provision,

It hangs on Initializing AML plugin.
Any advice on that? It’s annoying as I am unable to use my phone after the latest update.
