Very strange crashes using Ubuntu Oneiric and Debian Wheezy demo images ( Beaglebone Rev.A3)

Hi all,
I tried using the ready/pre-compiled image for Ubuntu Oneiric and Debian as they are described for example here http://elinux.org/BeagleBoardUbuntu#Demo_Image
I get very strange errors after using apt-get update apt-cache search apt-get install bzip2 or lsusb. I tried different revisions fo the images.
I guess I am not setting up something correctly related to memory usage or swap space but since I use a demo image and everything is ready I cannot understand what might be wrong.
Any help is appreciated. Thank you in advance.

One example of error is this :
