Hi,

trying to upgrade from 2.99.11 to 2.99.13 (using newly built
toolchain) results in the following messages during early startup:

Booting the old kernel works as expected.

Any idea what might be going on?


Here's "objdump -h" output from the bad kernel:

As far as I can see, at this level these two appear fairly similar.
