as the subject says: I'm using 2.6.14-git8 (also happens with -git7)
and dvb-kernel head cvs from today.
technotrend dvb-s ff 1.5 and a technotrend budget.
firmware for the ff card is the one provided by dvb-kernel.
(makelinks has been used to created the links to the kernel tree)

the oops happens after dvb-ttpci is loaded.
