I have this problem with recent 2.6.10 kernels too, but it has nothing to do with load in my case; it happens whenever I switch my KVM to the linux box. Long ago and far away, it used to be that switching out of X, then back in (ctrl-alt-F1, then ctrl-alt-F7) would reset the mouse and stop the jumping. At some point in late 2.4/early 2.6 that stopped working, and the only fix was to unplug the mouse from the KVM switch and re-plug it. In Oct 2004 I posted to lkml with subject "KVM -> jumping mouse... still no solution?" Dmitry Torokhov (hi :) responded that this would work on 2.6.9-rc3+: echo -n "reconnect" > /sys/bus/serio/devices/serioX/driver That was GREAT and it worked for a while, but now my last few 2.6.10 kernels don't seem to care when I do that, and again, unplugging the mouse is the only thing that works. I'm currently running 2.6.10-gentoo-r6. -Anthony DiSante http://nodivisions.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
