What was > that parameter. I see that "nokaslr" will disable it at run time. I remember that we had discussions that it can be used as a work around. But I don't see kexec-tools or fedora kdump scripts appending "nokaslr" in kdump case. That's strange. Chao, would you remember anything about it. Thomas, can you please test kexec with "nokaslr" specified in command line. This can atleast get you going for now till the problem is actually fixed.
