I believe I have this same problem and it is worse than ever in lucid 64bit 10.04. I'll try some mainline kernels but this bug in the kernel bugzilla is the same problem I think. https://bugzilla.kernel.org/show_bug.cgi?id=13405 Although I have some improvement with the kernel parameters indicated in this bug and other similar reports noapic or acpi=noirq they do not fully resolve the problem. I think it is also made much worse when the proprietary Nvidia drivers are added, in Lucid the USB keyboard locks. Before installing the Nvidia driver I had problems with one USB mouse and swapped to a different one and that worked.
