Thanks Kevin,

I did see these too. But at the same time, as far as I can see, the
qcom_defconfig boots just fine - indicating that this particular
commit would not be the cause.

I'll fire up some builds to figure out what's going on.


PS. I believe earlycon would be more helpful than earlyprintk on the
multi platform build command line...

Bjorn
