Description John William 2000-08-29 01:13:14 UTC
Kernel 2.2.16. I have added an ISA PnP modem. It is configured 
as /dev/ttyS1 using IRQ3. However IRQ3 does not appear in /proc/interrupts.

Otherwise the device works fine.

Comment 1 Alan Cox 2000-08-29 21:41:51 UTC
Does it appear in /proc/interrupts while you have it open (eg while online) -if
so then its not a bug but a feature. Linux knows how to reuse the IRQ for other
things when not using that port.

Comment 2 John William 2000-09-01 01:40:20 UTC
Alan - you're right, it does appear in /proc/interrupts while the device is 
actually in use but not at other times.

I was confused because it doesn't appear in /etc/isapnp.gone either so unless 
the device is actually in use it's "assignment" to IRQ3 does not appear 
anywhere.
