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

When it panics, I see this:

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. :^)

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.
> But no more oops. :^)
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.
