From 355fe568e285815e6f62fcd004ca80085ae46a69 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 27 Aug 2013 16:02:18 -0700 Subject: Revert "OMAP: UART: Keep the TX fifo full when possible" This reverts commit c4415084218c68c5ee2fc583431e89a78d896b19. Kevin writes: Hmm, another OMAP serial patch that wasn't Cc'd to linux-omap where OMAP users might have seen it. :( I just bisected a strange problem in linux-next on OMAP3 down to this patch. Reverting it fixes the problem. On OMAP3530 Beagle and Overo, after boot, doing a 'cat /proc/cpuinfo' was not returning to a prompt, suggesting something strange with the FIFO. Hitting return gets me back to a prompt. Greg, this one should also be dropped from tty-next until it can be further investgated and the problem solved.
