Hi, I am dealing with a problems with suspend/hibernate freeze during resume when DVB API is used. I found a workaround for it here <http://forum.xbmc.org/showthread.php?t=71490> which solve the problem but this is not a solution only a workaround. Problem is that when using USB DVB tuner the tuner is turned off/on during the suspend process, meaning that during the resume the USB disconnect and probe methods are running. The disconnect method is causing a call to dvb_unregister_frontend (or, if changing the order to dvb_dmxdev_release) This call hangs on wait_event until fepriv->dvbdev->users will free all users. This works fine when application is not playing the video, but if an application receives TV (tested with VLC and Kaffeine but true to all) Users will be free only when the application stops. It works if the device is plugged out during video display (users will be released when application closes the frontend and than the device will be free) but during the resume process, user interface is not working and there is a dead lock system must be hard power off and on. The workaround just causes the application to close force before the suspend. Since I only have Siano devices at hand, I couldn't prove if the problem is with our driver or in all USB receivers or only related to Siano driver, but exploring the code it seems that everybody are working in the same way. Can anyone approve that suspend and hibernate works fine when DVB is being watched by an application?
