Hello, I have an IGEPv2 revision 6 board, which uses the DM3730 OMAP3. With 3.2 omap2plus_defconfig, the system boots fine and have a working shell on ttyO2. On either 3.3, 3.4-rc5 or arm-soc/for-next from Arnd, the system boots all the way up to showing the shell prompt, but I can't type any character, as if UART RX was broken. All the kernel versions have been tested with identical bootloaders and identical setup, so there is apparently no misconfiguration of my serial terminal program regarding flow control or things like that. I have seen that there has been multiple changes to the OMAP UART code between 3.2 and 3.3, but a git bisect attempt has failed miserably due to numerous build issues in the OMAP code at various points of the bisection. I am attaching the boot logs for 3.2 (working), 3.3 (not working) and 3.4-rc5 (not working) in case this is of any help.
