So far everything is looking very good- haven't had a single failure in almost 
2 days now. So all my work on the en50221 implementation was pretty much 
wasted, at least I understand now how things work. :-) Tomorrow I'll start 
testing with vdr no longer bound to one cpu core and see how this goes.

By the way, I hope you don't mind but I've extended your patch a bit to close 
the few remaining locking holes which could cause a race condition. You find 
it attached to this mail. Basically I've expanded the locking for the reset 
function and added locking for the remaining relevant functions. It's still 
untested because my system is currently busy but I'll have it properly tested 
tomorrow. Just wanted to already get some feedback on it.

Thanks for taking the time by the way, it's really appreciated!

So long,
