port config is 115200 8N1. I don't recall doing anything special. I
boot, login, less file and get a lock.
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.
I'll test your config and go through the differences.
So far it looks like it isn't in the config. I've tested both your and
my config on debian wheezy on a boneblack. No lock ups.

Less doesn't fill my entire screen, so it looks a bit funky when
scrolling, but I'm not sure if that's related to the driver.

I'll have to look further for things we did that may have impact here.
Thanks,
Frans
