The kernel I am using is here:
(add tarball from kernel.org)

This is near identical to the 4.4.6 version I was using before,
but with fixed up SELinux configuration. I haven't re-tested
PCIe add-in cards, but back when I was running 4.4.6 I, too,
was having issues with immediate kernel panics when the driver
for a SATA or SAS card loads (tested with SIL3132 SATA card,
and 3ware SAS card).

I never managed to get to the bottom of it, or re-test with
4.4.7. I can confirm that CentOS shipped 4.2.0 kernel works,
and the main difference is that that comes configured with 64KB
pages. So it could be that this masks the bug that makes the
kernel panic as soon as a PCIe card driver is loaded.

I haven't had a chance to file a bug report regarding this
on kernel.org yet.
