I installed 9atom downloaded from Erik's site on 5/12 on a Gigabyte GA-D525TUD (http://www.gigabyte.com/products/product-page.aspx?pid=3549#ov).
When I have *nomp=1 in plan9.ini, I am able to log in and things work OK (except the mouse wheel scroll direction is opposite to what I would expect), When I remove *nomp=1 from plan9.ini, 9atom reports four processors, and every keystroke produces 6 or 8 or more tokens of the character I am trying to type. If I'm lucky and I tap a key lightly and quickly enough, I can get a single character, but it's not easy. I tried the only other usb keyboard I have and had the same problem. Any suggestions? Thanks.
