Right. My USB architecture is the same as you describe. I have also support EHCI, but I disable it now. The attach files are my kernel configuration and kernel oops while plug-in USB mouse.

I guess what you have is like this: --------- | MPC8241 | --------- | | PCI bus | -------------------------- | OHCI host controller(s?) | -------------------------- | | USB | ----------- | uPD720101 | ----------- | USB mouse So the IRQ is all up to your PCI setup and board wiring. Please send the output of ksymoops as described in linux/Documentation/oops-tracing.txt. Note that you need to run it something like this: ksymoops -v <vmlinux-of-target> -m <System.map-of-target> -t elf32-big -a ppc -K -L PS: Please check your PC's clock, your emails date back to July... -- Stefan Nickl Kontron Modular Computers -------------- next part -------------- A non-text attachment was scrubbed...
