Thanks. I have exactly those 2 patches applies as well. But on a
different git commit. And with some local (unrelated) patches as well.
I'll revert to exactly your version tomorrow and test again.

Good idea. I'm currently using a "dirty" local version. I'll try to
switch to an officially available version tomorrow. And send you the
version/git id.

I have a switch in between the target and my PC. But this network setup
is also quite "simple" and works with all other boards as well. So this
shouldn't be a problem.

I'm usually warm booting (pushbutton reset).

As mentioned above, I have some "homework" now to move to a
setup/configuration (official git commits) that you can reproduce on
your version C2 beagleboard as well. Stay tuned... ;)

Thanks,
