Ahhh. So that is why I failed to install the kernel! Thanks a lot.
I blindly copied .config from /boot/ to ensure I use the same config
options for testing.

I was going to try again, but noticed you already recompiled and
booted the kernel. I see ./test is running and there is nothing bad
in dmesg ;)

Thanks!
