I only turn on OHCI in kernel configuration, not UHCI.
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

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.
Thanks,
