The following patch was sent to this list back in May 2008
(http://linuxtv.org/pipermail/linux-dvb/2008-May/025952.html) and had a
followup of myself in October 2008.
As the kernel oops with USB DVB receivers happens again and again I want
to propose to finally apply this patch to the v4l-dvb repository.
Thanks,
-Thomas
