Note that I’m affected by this bug:
http://bugzilla.kernel.org/show_bug.cgi?id=8740
and I did set
# echo -n 1 > /sys/devices/platform/i8042/serio1/resetafter

I’m not sure if I did anything special to cause this. After this, the mouse
does not work any more, and
$ modprobe -r psmouse
hangs.


Greetings,
Joachim

nothing seems to have change since 2010: I don’t see a
NULL-pointer-dereference, but when both touchpad and trackpoint are
enabled, the pointer sometimes gets stuck for a short while while dmesg
tells me:

[ 55.444165] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1

I can prevent the problem by disabling the touchpad in the BIOS. This is
on 3.2.0-2.

Greetings,
Joachim

Thanks. Let's recycle this bug to track that.

Do you remember when the NULL pointer dereference went away? (E.g.,
does the 2.6.32.y kernel from squeeze reproduce it? A squeeze kernel
should work fine on a wheezy/sid system.)

I can’t remember (I disabled the touchpad and thus the problem would not
occur regularly). Is it important to find out whether squeeze is
affected, or can we just leave it at that, knowing that its fixed with
current kernels?

Joachim

Depends whether we want to fix it in squeeze. If you don't want to work
on that, I won't blame you.

as it does not seem to affect many people too badly, I’d rather not
worry about it.

Thanks,
