Completely on the same page with Timothy. Without the logs nothing could be
achieved. Please, could you post the logs?

I will give you couple of hints. You should have in GRUB both gentoo and
Fedora kernels (I am using Fedora for years, and completely switched two
months ago to Fedora 25 (today, it comes out as Final Release). Even I am
experimenting with rawhide (soon to be Fedora 26, with kernels 4.9.0 rc5
x86_64).

Here: when your gentoo kernel crashes, while rebooting, please, switch to
Fedora kernel, bring it up, and do the following:
journalctl -b -1 (latest log to shutdown).

For education:

I would like also to peak in them/latest gentoo logs (with Ooooops). ;-)

Thank you,
Zoran
