Looks like that device isn't properly being detected, but this shouldn't normally cause the kernel to lock up.

Reassigning to 'linux' so it can be looked at with the option driver or part of the serial stack. We've had this kind of issues before with at least the ZTE MF636.

Once freezes can be fixed it will be easier to make sure the support for the device works properly.
