The webmail reply broke the lines randomly, sorry for that. I have
resent a rebased version. And I also confirmed that in my case it was
SETUP_PCI caused the issue. Note, this SETUP_PCI is from previous
physical bootup, the old kernel reserved it in kexec e820, it is not
the RNG_SEED which was passed in by kexec. I believe the RND_SEED
region could cause issues only on the 3rd+ boot with a kernel without
the commit you mentioned.
It is a little tricky, I suppose not obvious to understand..
Thanks
Dave
