I have been having a few compatibilty issues with some of the cards I have installed on my system. So, I had to remove and reinstall them once or twice. Yet, I am getting more and more IRQ conflicts. The thing is that in my IRQ listing I have something like 5 or 6 devices called ACPI IRQ Holder for PCI IRQ Steering. So, I keep getting warnings about my devices conflicting with this thing. Why do I have all of these things? (Actually, upon counting, I found that I have seven of them. Each one is on a different IRQ.) Does any one know what these are?
