If anything, 2.6.25-rc6-git7 is even worse. Previously I've simply had delayed input, this time I had to actually kill the process, because it was unresponsive to keyboard input.
Here's the config file; I'm pretty sure I set it up correctly, (I just copied it from .24), but if I need to try it with any differing settings, let me know. [unhandled content-type:application/octet-stream]
