Subject: Some problems with Hauppauge HVR-1100 on 2.6.27

Hello,
I've having some problems with my Hauppauge HVR-1100 (cx88-based chipset). My 
DVB card works like a charm on 2.6.27-rc4 (full .config : 
http://omploader.org/veGd1) but doesn't work any 
more on newer kernels.

When i try to use my DVB card on 2.6.27.6, i get these errors in dmesg : 
divide error: 0000 [1] PREEMPT

So i tried another configuration according to the Gentoo Wiki and it still 
fails : 
CONFIG_DVB=y
CONFIG_DVB_CORE=y
CONFIG_DVB_CX22700=m
CONFIG_DVB_CX22702=y
CONFIG_VIDEO_CX88_VP3054=m
CONFIG_VIDEO_CX88=m
CONFIG_VIDEO_CX88_ALSA=m
CONFIG_VIDEO_CX88_DVB=m
CONFIG_VIDEO_CX88_DVB_ALL_FRONTENDS=y

So i'm stuck in an "old" 2.6.27-rc4 since i can't get my card working on newer 
kernels.

If you need anything, feel free to ask me. ;)

Thank in advance.
