RE: modem-manager hangs while starting up
Hi, it was not crashing, but simply doing nothing anymore (not detect any modem at all). It waits forever inside of poll and the backtrace Harald sent, was the place where the poll occurs.

Can you gdb attach to ModemManager and get a backtrace of where it's at?
Also, what kind of modem is attached? There are some devices that (due
to kernel bugs) block various file operations for about 5 or 10 seconds,
and that needs to be fixed in the kernel (option "send setup" blacklist,
to be specific). This might be one of those.
