Hi

I just noticed ModemManger consuming 100% CPU on one CPU core.

Took two gdb traces in that condition. I am not sure how I triggered this.

Hey, do you have by any chance a non-modem TTY that happens to send tons of data? Looks like MM may be for some reason choking while reading data from such a TTY.

Hi

I am not aware of any other TTY, nor have I set up any.
