Hi. I would like to do generic capture system which could be used for x86_64 and i386 first kernels. This system should be minimal, only capable to copy vmcore image over network for futher analysis. First kernel version is 2.6.23.9, I choose 2.6.16.y for capture. I have some problems with vmcore when origin is x86_64. With 32 bit kexec crash utility do not recognize it, when I use 64 bit kexec /proc/vmcore file has size == 0. Reading form oldmem is fine, I can for example get old dmesg from it. Now questions: It is possible to achieve valid vmcore when first is x86_64 and capture is i386 ? If no, is there some way to convert oldmem to valid vmcore in this scenario? Or maybe is possible to use crash with copy of oldmem (I try but without any success) ? Regards Stanislaw Gruszka
