Oops seen in dvb_usb_dib0700 when running 2.6.36-rc3

Just got up the courage to try the 2.6.36 series (indeed 2.6.36-rc3) and saw an oops from the dvb_usb_dib0700 module on startup. This is a Hauppauge Nova-T 500 card in a Compaq Alpha. Have never seen this when running 2.6.35 series or prior kernels.
