If I understand you correctly, you have a wrong view point in this situation. wait_event_interruptible cannot be called from interrupt context. Because interrupt context is atomic so you cannot sleep from it. A typical scenario is waiting from process context using wait_event_interruptible or derivatives and then in interrupt code waking up those processes. -- Bora SAHIN -- Kernelnewbies: Help each other learn about the Linux kernel.
