Netbsd 3.1, amd64,
>Description:
My notebook has an AMD dual 64 cpu, and kernel config file is generic with smp enabled and ohci disabled (because ohci will cause hangup of initial process). but when  I run startx, two lines of "pckbport: command timeout" will appear in ttyE0. And after a while in X windows, keyboard stops any response. 
The following is my dmesg:
