Hi all Ad I said in a previous email the current hibernation suppont has a problem with every interrupt line enabled in the previous session by modules. This kind of irq line after a resume will remain not initialized in the interrupt controller. The attached patch is a hack to close the issue ( and it works). I know it isn't a wonderful solution and it has to be taken as a momentary solution. The right thing should be add sysdev device to the intc but it requires more work in the intc design. Let me know. Regards Francesco
