The below link contain code snippets that process SONET events via an
interrupt. Basically an user space application waits on an ioctl call
for events that are queued. These events are queued via a kernel thread
that waits on a wait_event_interruptible call. When an interupt happens
the thread processes the events, timestamps them and puts a message on a
queue.
There is other code that is left out the starts the thread. If you are
interested...ask.
