This is still bad, I would prefer your Logitech mouse be identified
as such every time. Could you please try changing #undef DEBUG to
#define DEBUG in drivers/input/serio/i8042.c nad sending me 2 dmesg
oputputs - one when the mouse identified as "Generic" and one where
it is identified as "Logitech" - maybe I will see somethng there.
You might need log_buf_size=131072 kernel option to capture entire
dmesg and use "dmesg -s 131072" to dump it.

You can send the logs directly to me to not litter the mailing list.

This is good ;) Still it was somewhat a stop-gap measure - something
else is going on - it was not supposed to hit that place in the
code yet.

Thank you for testing my patch.

Yes, that did the trick.  The phantom PS/2 mouse is gone.  And I can still use 
either a USB mouse or a PS/2 mouse.  (It even boots a couple of seconds faster 
without the inital probe for the PS/2 mouse). 
 
Thanks.

Dmitry, 
 
Thanks for the quick response.  That fixed it. 
 
FYI, I still get 
input: PS/2 XXX Mouse on isa0060/serio1 
I booted 10 times, and "XXX" was "Generic" 7 times and "Logitech" 3 times. 
But no more oops. :^)

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
