2.6.7 oops in psmouse/serio while booting

[twl]

The panic happens in psmouse_interrupt.  It doesn't happen every time I boot, 
but it happens about half of the time.  It doesn't happen with 2.6.6. 
 
I have a USB mouse, but the input driver initially seems to think it has found 
a serial PS/2 mouse. 
 
When it boots ok, I see this: 
 
mice: PS/2 mouse device common for all mice 
serio: i8042 AUX port at 0x60,0x64 irq 12 
input: PS/2 Generic Mouse on isa0060/serio1 
<snip> 
input: USB HID v1.10 Mouse [Logitech Optical USB Mouse] on usb-0000:00:1d.0-1 
 
When it panics, I see this: 
 
mice: PS/2 mouse device common for all mice 
serio: i8042 AUX port at 0x60,0x64 irq 12
