Issue

Conficting hardware interrupts can make your life really difficult.
Fortunatly Linux makes it really easy to find out what interrupts
are in use.

Response

    - if you built a linux kernel that uses the "proc" filesystem,
      (editors note: rh has it as standard)
      you can determine which interrupts are being used by typing
      the following:

    # cat /proc/interrupts

     0: 60261763   timer
     1:   115429   keyboard
     2:        0   cascade
     5: 38999789   busmouse
    10:   160713   NE2000
    12:   386623 + BusLogic BT-946C
    13:        1   math error

      you can also get the i/o port ranges by typing
      "cat /proc/ioports".
