Hello David, I had the same problem having the same configuration on the qx0. You can solve it easily upgrading the kernel to the latest one 2.4.18 or Better the 2.4.21. You can find the kernel on Richard or Therry web. I am not sure about the cause, i think is due to not to the kernel version but to the kernel configuration about sharing interrupt parameter. Obviously you can also try to recompile the kernel version you have now. Let me know, i will try to help you if possible. Are you using Shoestring, the last q60 linux distribution ?
