DisablingInterrupts

This page describes how to make sure that the interrupts generated by the CBMIMO1 or ExpressMIMO card do not cause any conflicts with interrupts of the PC.

First you find out which IRQ the card is using: type 'cat /proc/interrupts' and look for the line which says 'yenta'. If there are other devices on the same line, you need to disable them. Usually each device has an entry in '/sys/bus/pci/drivers'. For example to disable 'uhci_hcd:usb4' go to '/sys/bus/pci/drivers/uhci_hcd' and type 'ls'. If there are multiple addresses, you need to find the one corresponding to the device in question. You can look in 'dmesg' for example. Once you have identified the address, lets say "0000:00:1d.0", type 'echo -n "0000:00:1d.0" > unbind'. Repeat this procedure until all interrupts that share a line with yenta are disabled.
