So, if I understand well, every times I send a request, I'm busy waiting for
the response while, when I allow disconnect I should be waken up by an IRQ ?
right ?

Now I agree with you.
I'm confused, what wrong ? I assumes that my IRQ (5 in my case) is well
configured (it's the same IRQ 5, MEM 0x140, base 0xCA000 on my NT box). What
can I do if linux can't send me a request via IRQ 5 ? How I can track that
(i.e. trace IRQ ?) is there a tool to show possible conflicts ? Should I
give up ?
