I'm pretty sure this is the problem I had.

I installed Lucid from scratch on a multi-boot system. (The upgrade from Karmic botched). Everything seemed perfectly fine except within half an hour, sometimes in only a few minutes, the mouse would freeze. My PS2 keyboard continued working fine, but nothing from the USB mouse. I tried plugging and unplugging and plugging in a different mouse but nothing would happen. There was still power to the USB but no response.

After some searching, I tried adding "acpi=off" to the grub boot options. Now it's working just fine.
