hi all,
I'm begin to learn the Kernel and i'm reading <<Linux kernel development>>.It says "This is an important point, always keep in mind that all interrupt handler has interrupted other code(possibly even another interrupt handler on a different line)".What i am not able to understand is how a interrupt handler be interrupted ? DID NOT it uninterrupted?

best regards?
