You (hopefully) can find it in your kernel sources and notes on how to use it at Documentation/hwlat_detector.txt. In short, you could be seeing long latencies spikes created by SMIs. That kernel module, hwlat_detector, may help you identifying them. The hint about setting the priority of the IRQ threads is also a good one. You should also look at the logs of the USB/firewire/whatever you are using to commounicate with your keyboard... you may be suffering buffer underruns due to file size or something similar to it.
