As discussed in IRC, this error message complains about too big kernel
image size which is different for overall image size.

Could you write a patch for this please, I am busy the next few days.

I think we should make the images smaller by deactivating
CONFIG_KERNEL_KALLSYMS by default and using some scripts to decode the
binary only stacktraces.
In addition we should provide more space for the kernel partition.
