keyboard driver missing key up event

$ cat /etc/redhat-release
CentOS release 5.4 (Final)

I've tried two copies of a: Microsoft Natural ergonomic Keyboard 4000 v1.0
Both fail. The result is my screen fills up with whatever key was missed.
Re-pressing the key does no good. I have to unplug the keyboard and then
plug it back in. So, I'm interested to know if this is a general problem or just
my system. Meanwhile, I'm turning down the key repetition rate so it doesn't
immediately fill my screen when it happens.....

I assume this is a USB keyboard? If so, have you tried another make/model (not Microsoft)? One possibility that comes to mind is that your BIOS is not configured properly. There are usually a couple of USB settings, including a "legacy" one for operating systems that don't know about USB keyboards so it will emulate a PS/2 device. That is not what you want for current Linux distributions for sure.

Yep, all three are USB keyboards. The problem got fixed by leaving the system shut down overnight. 8-O So that either changed hardware state or cleared some weirdo software state or some combination. (There don't seem to be non-Microsoft keyboards in this office, so non-Microsoft was a non-option. *Also* when I returned to the original keyboard *IT* showed the same problem, too. Rebooting didn't help.) Anyway, all better now, though I remain disconcerted about what actually happened. Thank you!

You must have been experiencing the BKOD syndrome (Blue Keyboard Of Death). It's sort of like the BSOD, but only affects Microsoft keyboards...
