USB problem on x86_64: nommu_map_single() issue?

[Nicolas Bareil]

Hi

On 2.6.27, I can't use any USB device (mass storage, mouse) anymore on my x86_64 system, the devices
are not detected: lsusb returns nothing except the hub.

I have the following logs in kern.log when booting with my USB mouse plugged :
