Did you forget to create an initrd? After installing the kernel, run:

$ update-initramfs -k KERNEL_VERSION -c

Please run some stress tests such as stress-ng and report back.

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.
