2.4.2-ac3 was fine. These are the only USB changes I see since then.

I rebooted with the new kernel and got an oops when the init scripts started looking for usb devices.

I don't have a serial console, so getting the oops takes a while. I'll send it if needed. I just loaded the mousedev and input modules. Plugging in the mouse oopsed again.
The first line of the oops is ---- kernel BUG at slab.c:1398! ----
Any other ideas to try?
