Public bug reported:
On insertion of a Huawei E173 mobile internet USB stick the artful
kernel now oopses:
BUG: unable to handle kernel NULL pointer dereference at 00000000000003d0
[ 633.710837] IP: pkt_setup_dev+0x2af/0x650 [pktcdvd]
Issue seems to be related to the setup of the cdrom-like device hosted
on the stick together with the UMTS modem.
May possibly be due to some race as the usb stick configuration keeps
changing until the device is properly switched to operate as a modem.
Some of the times, UMTS modem remains detected notwithstanding the
issue.
After the issue, the system has problems in shutting down, though.
