Where and how I should report this kernel panic and what other steps should I take prior to reporting? I guess I cannot report this directly to the upstream because I'm not running vanilla kernel.

Attempting to launch Steam client causes the kernel to panic. This is reproducible only with the "4.14.11-gentoo" kernel. I cannot reproduce the panic with the "4.14.10-gentoo-r1" kernel.

System:
AMD ThreadRipper 1950X
ASRock X399 Professional Gaming
32GB Memory (4 sticks)

Code:
GRUB_CMDLINE_LINUX_DEFAULT="rootfstype=ext4 pcie_aspm=off"


Reason for "pcie_aspm", "ThreadRipper & PCIe Bus Errors": https://forum.level1techs.com/t/threadripper-pcie-bus-errors/118977/27

dmesg log, recorded with netconsole:

Disabling "PAGE_TABLE_ISOLATION" aka, Meltdown patch, does the trick which is OK for me since I don't have an Intel processor. The kernel no longer panics.
