I have applied Henriks patch to both dvb and myth on a 2.6.15 kernel. I have
a Twinhan DVB-T card.

Sometimes the machine becomes unresponsive. I can't ssh into it, but I can
ping it. Since my TV is on repair, I don't have a local screen attached, so
I have to do a hard reset. This is what I find in /var/log/messages after
reboot (i am not even watching or recording anything):

After that the log is empty.
This is the only occurence of "dst_ci_command:  Write not successful, trying
to recover"
in the log.

Any ideas? How do I enable more verbose logging?
