Hello,
Thanks for the continuous help Karsten. I have followed your steps.
Using the sid branch and the orig file (4.14.13-1) from the debian linux
repo.
Unfortunately when I run the last command to build the package. It fails
after building the kernel + modules with the error message: "Can't read
ABI reference. ABI not checked!"
I guessed I might still miss one step :(
Thanks,
Loys
