So I booted my mini Debian 7.6 (basic system + openssh) on my beagle bone black which is: [ 0.000000] AM335X ES2.0 (neon ) configured a console, login, invoked "less file". The file was shown, I hit on the space key so less shows me more of the file. No lock-up. I tried booting via NFS and MMC. I tried various files with less. My dot config is here https://breakpoint.cc/config-am335x-bb.txt.xz If there is nothing specific to the file you do less on I have no idea what else it could if it is not the config.
