When moving the mouse, at times the mouse goes haywire and the pointer moves by itself clicking on things all over the desktop. Reproducible: Sometimes Steps to Reproduce: 1. N/A -- Random, but will not do it without the user doing something 2. 3. Actual Results: The mouse moved on it's own volition clicking on things on my desktop without any user input. Expected Results: Nothing. I just recently had this bug occur and open up 12 instances of Kwrite. It is a Logitech based PS/2 wheel mouse with IMPS/2 set in XF86Config. I checked /var/log/kern.log and found this error: Feb 6 05:18:34 Illusion spurious 8259A interrupt: IRQ7. Feb 6 05:18:35 Illusion psmouse.c: Wheel Mouse at isa0060/serio1/input0 lost sy nchronization, throwing 3 bytes away. Not sure if this should be sent upstream, but the doc's say to file with you first.

This is covered in the 2.6 input drivers FAQ. http://marc.theaimsgroup.com/?l=linux-kernel&m=107563039307153&w=2 Look for the information on "psmouse.c: PS/2 mouse at serio0 lost synchronization, throwing 2 bytes away.", it's the same issue. Closing this as CANTFIX, because it's not something we can sanely change ourselves.
Odd that this problem has only appeared in recent versions of 2.6 (for me at least) yet they blame my mouse (or hardware) as the culprit... Oh well, sorry for wasting your time.
It's not actually the mouse. Of course not. I had this same problem; and read the input FAQ several times over. My problem has now gone away - I disabled ACPI in my kernel. As the FAQ suggests. Try this, I think it may work for you too.
