I have recently upgraded my kernel to:
linux-4.14.65-gentoo

whenever I boot I get a black screen after grub.

I have the following VGA controller:
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 5500 (rev 09)

kernel config:
https://gist.github.com/adellinuxplus/f184cb8d8acd26889fd3c277c202da55

I found the following in my journal:

Can you post the output of the rest of the journal around the stack trace? How did you upgrade the kernel, with genkernel or manually?

Looking at the .config, you enabled CONFIG_FB but then didn't enable any framebuffer device.
The kernel oops is a warning, so probably unrelated.

Please post/paste the dmesg after boot.
EFI or MBR boot?

If you enabled efifb on the new kernel you might have run into the same issue that I just bug reported.
