high cpu usage by modem-manager

[tzg6sa]

Hi All,

I have a problem that the process modem-manager eats up all the cpu resources making it impossible to do anything on my PC. This issue is comes up randomly even during boot up and unfortunately very often. The twist in it is that I can not even kill the process using kill or killall (tried to kill even from top; of course with sudo)

How can I shutdown a process when kill does not help?
Is there any way I can disable to start this process during boot up?

Let me know if you need further info to help me solve the issue.

Thanks,
Zoltan
