Yeah, this is what I was expecting. I have already a patch that would fix
the issue with xc5000 (the issue is actually at em28xx, that needs to do
a full initialization of the device), but something else is needed to put
drxk into a reliable state.
I am traveling during this week (without the HVR-930C or RF generators).
So, I can't touch on it. I'll seek for some time to try to fix this issue.
Regards,
Mauro
