This isn't
supposed to happen with PCI but it looks like it is in your case.
Regarding what Neil said...you can try cat/proc/iomem
The following are /proc/interrupts and /proc/iomem on the current
configuration. I am not sure what I am looking at with the iomem
output.
/proc/iomem shows you a map of memory space. The addresses are the
start and stop boundaries of a block of memory used by a device to
communicate with the system. These blocks are fixed in place and the
addresses are absolute addresses. For example, see the BIOS >
000f0000-000fffff : System ROM. This will be the same for every PC.
Other parts may vary, but the video BIOS (ROM) is usually the same also.

This part looks good. You have a separate IRQ for both the ethernet
cards and the sound card. Leave the system as is for further testing.
The interrupt load for the video capture card (bttv0) is up a bit. I'm
guessing it does just frame capture and no hardware compression.
This must be an older motherboard because it doesn't have the APIC
(Advanced Programmable Interrupt Controller) interrupts.

This shows that the wireless PCI card is using the orinoco driver.
What is the output of lspci? You can use that to match with the
/proc/iomem map to see what device is using which part of the memory
range.
Gus
Here is the output of lspci. My take here is that the /proc/iomem and
the lspci agree on the memory for the wmp11. For the sound card the
lspci displayed a port in place of a memory address and I can't figure
out how to match it to the iomem output.

The mother board is rather old, I think I bought it in late 2001. The
TV card is an old wintv Bt878 that has no hardware compression but it
works great with tvtime.
