[linux-dvb] Kernel 2.6.7 Oops with Hauppauge rev 2.1 and budget

[Florian.Steinel@t-online.de (Florian Steinel)]

Hi List,

when unloading and loading the dvb driver for Hauppauge PCI rev2.1 and 
Hauppauge WinTV-NOVA-S, i get:

did i miss some patches? Is maybe modprobe 0.9.14 to old?
lsmod also hangs.
I can also reproduce this bug, if needed (as i found 5+ traces of this 
Oops).
