ncsw_config.mk missing from linux-lowlatency kernel

[Forest]

I'm on Ubuntu Studio 14.04 Beta 2 (upgraded through apt-get from Beta 1,) and I'm trying to compile my own low-latency kernel with make-kpkg. I just want to remove xhci-hda and ehci-hda from the kernel so my USB Audio Interface will work correctly. I modify the config file via make menuconfig, but then when I run

sudo make-kpkg clean

I get the following output:

exec make kpkg_version=12.036+nmu3 -f /usr/share/kernel-package/ruleset/minimal.mk clean
====== making target minimal_clean [new prereqs: ]======
This is kernel package version 12.036+nmu3.

The same thing happens with 3.13.0-20-lowlatency as well. I have the build-essential package installed as well as linux-headers-lowlatency and linux-headers-generic. I think the device driver is just missing.

Perhaps this is relevant to this bug. I just ran

sudo apt-get update
sudo apt-get upgrade
sudo apt-get -f dist-upgrade

and thereby installed the new linux-headers-3.13.0-22-lowlatency. In the process, I get these errors:

Two weeks later and this problem persists. It basically makes my computer unusable for the purpose I bought it, which is making me really angry at Ubuntu. What kind of distribution ships a buggy usb3.0 driver built into the kernel (rather than as a module)??

I got desperate today and tried making a fake ncsw_config.mk file. I just went to that directory, opened a blank file in ncsw_config.mk in vi, and then saved it. When I ran make-kpkg clean, it accepted the fake file, but then told me

/usr/src/linux-headers-3.13.0-24-lowlatency/ubuntu/aufs/Makefile:2: ubuntu/aufs/magic.mk: No such file or directory

so I went to /usr/src/linux-headers-3.13.0-24-lowlatency/ubuntu/aufs/ and again made a fake magic.mk file.

Now I was able to run make-kpkg clean without any errors. I have to run it with sudo though because with fakeroot I get errors because various permissions are denied. Then I tried running

sudo make-kpkg --initrd --append-to-version=.041514 kernel_image kernel_headers

and I get the following output:

Hey, a bug I filed 4 years ago has been marked as "won't fix". This is
precisely why I don't use Linux anymore...

The bug was marked as "Won't Fix" because the bug is based on a version of Ubuntu Studio that is long-since past it's End-Of-Life date (For 14.04, that would've put it EOL in April of 2017). If this is still a problem in current, supported versions (16.04 until next month, 18.04, and 18.10), please file a new bug report.

[Erich Eickmeyer (eeickmeyer)]

Additionally, the bug is still open in the kernel, but the kernel is no longer maintained directly by the Ubuntu Studio team and hasn't been for years.

[Erich Eickmeyer (eeickmeyer)]

The original bug had to do with self-compilation, which isn't even valid against an already compiled kernel. Appears to be a support question more than anything, and per rules, marking as "Invalid."
