I am trying to run down a problem with a PVR-500 card. I noticed in dmesg that the second tuner on the PVR-500 appears be assigned to IRQ 3. As I understand it IRQ 3 is normally assigned to COM port 2/4. Is there a way to get a list of IRQ assignments that have been made under FC4? Trying to figure out if the IRQ assignment is part of the problem with the second tuner on the PVR-500 card not working.
