The card is working again. I'm not sure whether I did
something to help it out or whether it just works after
10-15 reboots :-)
I am now running the latest [stable] driver and firmware
from ATrpms. I took the source rpm and rebuilt it for my
system (Debian).
KnoppMyth has a set_ivtv_params script in /etc/init.d
which runs during boot before myth backend starts. I
edited it so that it sleeps for 45 seconds and doesn't
call test_ioctl any more. I've noticed that regardless of
what input you select in test_ioctl, it always reports
(dmesg) that its selecting Composite Video. I assume that
the message is wrong, but maybe it really is selecting
the wrong input.
At some point when I'm feeling adventurous I'll reboot the
box a few times to see if the M179 always works now or whether
I just got lucky. Since this isn't a test box, I think its
time to leave well enough alone for the moment.
