Sep 24 11:57:56 ubuntu-phablet kernel: [ 180.498000] tabla_codec_enable_chmask: Slim close tx/rx wait timeout
Sep 24 11:57:56 ubuntu-phablet kernel: [ 180.498641] tabla_codec_enable_slimrx: Disconnect RX port ret = 0
Sep 24 11:57:56 ubuntu-phablet kernel: [ 180.501449] overflow error on port a, value 5

I believe this indicates some type of kernel error. I don't mind if anyone takes a look at the kernel to see if this scenario (tearing down a voice call with streams running) can be handled more gracefully, but I don't think it's urgent, because we have a working fix/workaround in PulseAudio (close the streams before tearing down the voice call).
