Hi,

Thanks for your answer, but a tasklet runs in interrupt context
(in_interrupt() != 0) so it doesn't support schedule() call
included in "down" semaphore function.

Any other idea ?

Laurent.

As the interrupt handler can't be scheduled, I have made a

which waits forever on a semaphore.
This semaphore is set when a received packet interrupt occured.

You should look into tasklets for this. Not that your system is not
OK, but, as you said it, it's not fast enough.

Note that you still have some limitations using tasklets, but it's
more flexible than Interrupt handlers.
