What are the usb-driver-quirks that you mention? Are they usb DVB devices that 
you have?

I've just been having another go at getting software suspend to work on an 
Epia-based vdr system with vdr-xine. I can get it to suspend and resume 
fairly easily with a 2.6.12 kernel and the latest patch set form but I can't get the DVB drivers to play nicely!

A suspend and restart brings it back up as it should and vdr starts but all I 
see is a black screen. I can change channel but I still get a black screen. I 
have yet to see if the DVB card (an old l64781 based Nova-T) is outputting a 
stream or not, and LIRC won't allow any connections after resuming (homebrew 
receiver). I have yet to try playing back a recording because it's a bit 
awkward without a remote!

Has anyone had any luck with software suspend and this type of card or LIRC? 
Do I need to explicitly kill vdr and unload the drivers before suspending, 
and then reload and restart on startup?
