OK, that indicates an issue with the serial port rather than anything to
do with the dom0 configuration.

I'm going to assume this isn't a h/w issue and that you've tested the
serial port works e.g. with native Linux? It could also be a RTS/CTS
misconfiguration between Xen and the host terminal emulator, I suppose,
so that's worth checking.

Otherwise it seems like the issue is either with the Xen serial port
driver for your platform or with the DTB description of hte IRQ or
something like that.

J6 EVM is an Omap5, right? With the same UART as people have reported
successes with on other OMAP5 platforms e.g. at
http://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/OMAP5432_uEVM
 ?

Please could you post a full serial log of the boot, perhaps that will
give us a clue.

Ian.
