I am getting the same kernel panic referenced here in the lkml: https://lore.kernel.org/lkml/20200423161126.GD26021@zn.tnic/
note my machine in SMB
As a workaround you can disable stack protector as in config: CONFIG_STACKPROTECTOR=y CONFIG_STACKPROTECTOR_STRONG=y Or use proposed patch.
Created attachment 637146 [details, diff] patch for gentoo-sources-5.6.11 compiled with gcc-10.0.1 I think this patch is committed to fix the early panic. I can confirm it fixes the issue on my computer
