Followup-For: Bug #883938

Dear Maintainer,

I did bisection of upstream kernel between 3.16.48 and 3.16.51
The problematic commit was: cbff7ea5d47aa15e1b6d8063bd147cc0a289e452
 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?h=v3.16.51&id=cbff7ea5d47aa15e1b6d8063bd147cc0a289e452

In our case, the panic happen on very big iron servers:
 * Intel 44 cores, used with HT (88 logical CPU's)
 * 120Gb RAM

It happen very early during boot -- right after CPU enumeration.
The panic trace indicate its related to scheduler initialization.
