Unless I did something wrong, it's apparently not in the USB subsystem.

I have 2.6.12-rc3 and rc4 compiled. Same config file on a test system.
again, rc3 works, rc4 does not. I booted rc3 and force loaded the usb
modules from rc4 into rc3. It tainted the kernel, but it worked.

I booted into rc4. I do have ACPI compiled so I added acpi=off. This did
not work, same problem as before. I left a ping running, the usb controller
was on IRQ 9. The test system is an old NEC notebook with an Intel chipset
(thus uhci-hcd usb1.1). I plugged in a Belkin USB2.0 cardbus card (USB1.1
is serviced by ohci-hcd) and plugged the ethernet adapter into that. Same
problem.

As far as controllers, ALL except 1 (The cardbus USB2.0) has been some
version of Intel. I have tested this on 4 different systems with the same
results. An MSI 6163 board, a Supermicro X5DA8 board, a Dell Inspiron 8100,
and the NEC Versa FX. The Supermicro is running SMP, but I doubt that
matters.

At this time, it's late. I'll see about reverting files from rc4 back to
rc3 to see which one causes it to work again.
