This same problem showed up on my friend's computer. We fixed it by changing the reboot code (I believe it's hard_reset_now(); )to:
xor %esp,%esp inc %esp push %esp
That works on every x86 machine we've tested it on, including his with the wacko keyboard controller, it's about as non-portable as it gets though, so I doubt its suitable for the actual kernel, you should try it in your machine, tho.
