Last week I installed FreeBSD 4.5 (though I noticed the same problem on 4.3 and 5.1) on a Presario 1230 laptop.
During installation and afterwards I noticed a slow keyboard response on the console. Scrolling of long output (cat big_file.txt) works perfect or comparable to a Linux installation. Only while typing (no system load) I notice a minimal time lap between pressing the key and the showing up of the character on the screen. The effect is the same as when remotely logged into a slow machine or via a slow / busy connection.
Unfortunately the problem isn't related to the key repeat rate (thanks anyway Nathan) so a
$ kbdcontrol -r normal/fast/slow
doesn't fix the problem.
I realy need some help here so any input is appreciated (remember I'm a FreeBSD newbie, so maybe I overlooked something trivial)
