Doing the same on 2.6.0-test9-mm1 & 2.6.0-test9-mm2 moves the mouse only about 30 pixels, or about 1/33 of the way across the screen. It is exactly the same system, with exactly the same configuration. The only difference is the kernel. On 2.6.0-test9: ... mice: PS/2 mouse device common for all mice input: PS/2 Generic Mouse on isa0060/serio1 serio: i8042 AUX port at 0x60,0x64 irq 12 ... psmouse.c: Mouse at isa0060/serio1/input0 lost synchronization, throwing 2 bytes away. On 2.6.0-test9-mm2: mice: PS/2 mouse device common for all mice PS/2 Generic Mouse on isa0060/serio1 serio: i8042 AUX port at 0x60,0x64 irq 12 Note that I don't seem to get "lost synchronization" messages with mm1 or mm2. Also, it might be important to note that every now and then, my cursor "goes crazy", flying all over the screen and pressing random buttons in response to normal user input. Releasing the touchpad for a few seconds invariably fixes the problem. I think it is related to these messages in the log: Nov 5 21:02:36 localhost kernel: psmouse.c: Mouse at isa0060/serio1/input0 lost synchronization, throwing 1 bytes away.

This spurious motion does NOT happen in mm1 or mm2, but it DOES still happen in 2.4.22-10mdk.
