This seems to have fixed the firmware loading problem - using the latest CVS driver, with ttusb_dec dated 4th January, I can get the driver to install successfully, the digibox re-boots and shows the blue splash-screen on the TV, but then stops and shows a black screen on the TV.

When running tzap to tune in a TV channel, the kernel throws an oops.
I've tried to use ksymoops to produce a useful debug listing, see
attached.

Whereas the raw 2.6.0 kernel from kernel.org crashed when the ttusb_dec
module was loaded in debug mode, the CVS version crashes either with or
without debug=1, but only when running tzap after device initialisation.

Thanks,
Michael

ksymoops 2.4.9 on i686 2.6.0.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.6.0/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
No ksyms, skipping lsmod
