Could you please take a look? I got hold of a Beagle, a sticker on which says rev C1D. Not sure if there is a better way to identify the rev, but this one seems to boot fine for me even with this patch. I just applied this one patch on top of the the tag 'integration-2.6.39-20110310-008' of git://git.pwsan.com/linux- integration. Would a board rev make a difference? ------- Starting kernel ...
