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.
