Looks related to the comment I wrote here: https://bugzilla.yoctoproject.org/show_bug.cgi?id=1892 I have a slightly different failure with yocto 1.2 beta snapshot (same kernel) but seems related. Needs more investigation. Anyone else having problem booting on beagleboard xM? Seems something wrong happened after 1.1 release...
