Subject: 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.
