this happen with eci adsul usermode driver. pppd crash with this oops on console.
The field dev may be reseted so the the line 321 of usb.c
("dev->bus->bandwidth_allocated += bustime;" in fuction usb_claim_bandwidth) rise the
oops.
But I don't really see where the dev field may be reseted so I guess the crash is due
to a race condition on the urb sent int endpoint as the
uhci_submit_urb proc release a spinlock just before.
