Comment 1 for bug 1013204

the simplest method to reproduce it:

get an O omap4 preinstalled image

http://cdimage.ubuntu.com/releases/oneiric/release/ubuntu-11.10-preinstalled-server-armel+omap4.img.gz

install it on your sd card (follow the installation instruction), then reboot the board and let it reach the login prompt:

Ubuntu 12.04 LTS panda ttyO2

localhost login:

at this point, try cut&pasting a long line of text (>= 10chars will do it), if it doesn't get through intact, you are affected.
