Bug#762783: Acknowledgement (ftdi_sio: kernel OOPS, ftdi_sio_port_probe+0x2dc/0x43a)
I could add information using the 3.13-1-686-pae kernel (on an eeepc 701).
In such case, the ftdi_sio module should be loaded first and then configured as:
$ echo 0421 0264|sudo tee /sys/bus/usb-serial/drivers/ftdi_sio/new_id
Then the OOPS arise... but the system does not hang (much better):
$ echo 0421 0264|sudo tee /sys/bus/usb-serial/drivers/ftdi_sio/new_id
0421 0264
