[Voyage-linux] kobject (cec84330): tried to init an initialized object, something is seriously wrong

[(spam-protected)]

Jean-Pierre,

 I have a similar problem (usb links dropping out regularly) when using
the Sierra Wireless MC8790, and another user reported a similar problem
when using the Sierra Wireless MC8775.

 This problem occurs with Voyage 0.6.x and not with Voyage 0.5.x or with
Zeroshell linux.

 By stopping the udev daemon, it is found that any udev/hotplug messages
are a result of the problem, not the cause of the problem.

 My suspicion is usbserial.ko, the USB serial generic driver, maybe
doesn't handle an interrupt correctly.
 Haven't had time to check the source code for what changed.
