The fix was to add some spin to the spin loop in the keyboard routine (you could actually fix it by manually editing the binary for the input routine). This used to manifest itself on the IBM 300 series desktops regularly. Does FreeBSD use something as horrendous as a spin loop in the keyboard entry routine? Maybe you can try changing the loop timing. ====================================== When philosophy conflicts with reality, choose fantasy.
