Hi all, as Frank asked, I compiled myself a kernel using his latest commit identified as good: 67e306c6906137020267eb9bbdbc127034da3627
and this kernel works, but then fails to load initramfs. I don't know if the crash was before or after, so if it is a "proof" that it is good or it is not conclusive? The good news is that latest kernel installed seems to boot and takes all CPUs online. How stable it is I don't know, it needs to be tested.
