I pxeboot into a bzImage, kexec into vmlinux, and then repeat kexecing into vmlinux. At this stage the kexec vmlinux operation sometimes files. > Here Rachita is running into some strange issue where kexec on a x86_64, > EM64T machine is failing. It seems to be hanging somewhere in purgatory. I remember having problems using kexec on a certain AMD64 box but the same kernel worked just fine on the dual opteron machine sitting next to it... I assumed some kind of chipset problem back then and moved on to more fun things. =) > She is using 2.6.21-rc2 kernels and latest kexec-tools.

It is not so strange that we experience problems IMO. There are multiple one-off errors all over the kexec-tools code tree. And maybe x86_64 machines are more likely to be equipped with exotic memory configurations that triggers certain bugs, who knows.
