Hi All,

After a dist-upgrade my HDTV7 Dual Express card stopped working.  I managed
to get it to work before, from the logs from Dec 15:

Dec 15 23:47:47 cheetah kernel: [   10.701054] cx23885 driver version 0.0.1 load
ed
Dec 15 23:47:47 cheetah kernel: [   10.701117] ACPI: PCI Interrupt 0000:02:00.0[

Dec 15 23:47:47 cheetah kernel: [   10.701237] CORE cx23885[0]: subsystem:

Dec 15 23:47:47 cheetah kernel: [   10.870102] cx23885[0]: cx23885 based dvb card

That was with linux-image-2.6.26-1-amd64_2.6.26-11_amd64.deb and compiled the
cx23885 module from the mercurial repo.

The current kernel is from: linux-image-2.6.26-1-amd64_2.6.26-12_amd64.deb.
I pulled the mercurial sources again did make and make install, rebooted but
I still get:

Dec 20 13:15:02 cheetah kernel: [   11.801129] cx23885: disagrees about
version of symbol v4l_compat_ioctl32
Dec 20 13:15:02 cheetah kernel: [   11.801133] cx23885: Unknown symbol
v4l_compat_ioctl32

I have seen this before, but I cannot figure out what is happening.  I would
appreciate if someone could explain to me what is going on here.  That may
reduce my frustration somewhat.

If there is some documentation on how to debug a problem like this I would be
willing to do some debug and even work on it.  I suspect that the kernel
interface got updated and changes for the driver is needed.  Maybe this is a
simple enough project to get started with open source.  (Let me know if
not...)  I have not contributed to open source yet, so please be gentle.

I tried reinstalling the old linux-image package but that now does not work
either.  There must be some other software/libs that got updated from apt-get
dist-upgrade rendering the cx23885 module unusable at the present.

Any insight would be appreciated.
