I suggest that you try compiling your custom 5.13 kernel on a system that runs a 5.13 version of the kernel itself.
This can be Ubuntu 22.04 or Ubuntu 20.04 with the HWE kernel.

Sorry, no idea.

Do you need KCSAN? If not, then you can disable it. Maybe the compilation works then.

Hi m-hampl,
Thanks for reply.
I was disabled KCSAN but issue was not solved.

If check-config fails, you should try executing editconfig first
see e.g. https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel#Modifying_the_configuration

"you need to go through each (Y, Exit, Y, Exit..) or get a complaint about config later"

Hi m-hampl,
