This is entirely possible. PCI allows this. My home machine has 3 seperate
devices on the same IRQ. It works fine.
However, this will make troubleshooting the problem much more difficult.
Would it be possible to shutdown the network, cat /proc/interrupts, plug
in the device, wait until it fails, cat /proc/interrupts again and get
the output of both?
