2.6.6.-mm3: OOPS from usbserial (?) at boot time. Maybe preempt related

[Martin Knoblauch]

Hi,

 with 2.6.6-mm3 I get the following OOPS at boot time. Could be preempt
related I guess. No time to check with preempt disabled right now.

 Config is included.

usbcore: registered new driver usbserial
drivers/usb/serial/usb-serial.c: USB Serial Driver core v2.0
Unable to handle kernel NULL pointer dereference at virtual address
