How NEC uPD720101 USB chip work well on linux2.6.12

[JohnsonCheng]

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,
Johnson Cheng

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...
