Horrible mouse performance

Hi,
When using the linux 2.5.45+IA64patch kernel on an I2000, the mouse
pointer lags actual mouse movements by a long time, making X almost
unusable. I haven't configured in the frame buffer, if that makes a
difference.

There certainly are problems with the input layer in 2.5. So the keyboard is actually working for you? That's better than it used to be! ;-) Both mouse and keyboard are connected via PS/2, not via USB, I assume?

(I don't normally see such problems because I do most of my 2.5 work remotely, without console access.)

Yes, this is on an I2000. I'm trying to see if preemption support makes any difference. But the interactive-via-X performance is so awful anyway, that I can see no difference.

Have you tried using a USB mouse/keyboard? That seemed to work much better for me last time I tried.
