It has been shown that the autosuspend delay for this device enacted
by modem manager will race with suspend and cause system suspend
failures.
This occurred in ChromiumOS on a chromebook, but there is no reason
it won't happen in regular notebooks with the same WWAN. To avoid
the failure delay autosuspend to a frequency longer than the polling
rate used by modem manager.
