That sounds like the right thing to do.So basically kexec on panic path seems to be clean except stomping issue. May be bzImage program header should reflect right "MemSize" which takes into account extra memory space calculations.I remember trying to compute a good memsize when I created the bzImage header but it is completely possible I missed some part of the calculation or assumed that the kernels .bss section would always be larger than what I needed for decompression.
Could someone please describe the intended semantics of this MemSize header, *and* its intended usage?
