Does it power down after few tens of seconds?
If so, I've seen this same issue few times after having my panda
powered off for a while, for example over the weekend.
What I've noticed is that leaving just u-boot prompt running
for a few minutes cures the problem somehow.. After that the
kernel will boot just fine.

Tony
