As someone who has some experience compiling kernels, I think in general supporting custom kernels is beyond the scope of askubuntu.

Perhaps on other stack exchange sites, I am not sure.

The reasons are  :

1. As far as I know, the Ubuntu kernel team does not support custom kernels.

2. The Ubuntu documentation clearly states custom kernels are not supported.

3. Compiling a custom kernel involves a configuration file with 6,000 lines of options, let alone actually modifying the underlying C code. Many of these options are hardware dependent and the Ubuntu Kernel team already releases a kernel that is already very generic.

4. Actual kernel bugs, if they exist in the code, are reported to kernel.org. The ubuntu kernel team supports only a minor portion of the code, such as apparmor.

As with all rules, there may be some exceptions such as applying a patch or perhaps a trivial configuration change, that could be considered on a case-by-case basis.

In summary, in general, IMO custom kernels are highly specialized and it is easy to break, and hard to fix a kernel  .config
