[linux-dvb] Nexus-S Oops when used on a 3.3-volt bus

I recently put together a system which consists entirely of 3.3-volt
PCI 2.3slots. All modules load successfully and recognize my Nexus. I
can do an
femon without issue. However, when tuning the card I get an oops. Can anyone
point me in the right direction? The Nexus is keyed for 3.3-volt PCI, is it
not compatible? Am I barking up the wrong tree here?
