Comment 11 for bug 2065838

I have tried building an unpatched kernel a couple different ways including following the direction from the recommended link (https://itsfoss.com/compile-linux-kernel/) but failed to produce a bootable kernel. The kernel appeared to build correctly as I did not notice any compile errors, but once installed, it failed to boot. I am unsure how/where to check the build logs (I still have the failed session so I can review if needed.)

Following my notes from previous successful kernel builds (to fix sound issues on my Lenovo laptop):

*Ubuntu version:

1) install kernel build tools:
(https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel):

* sudo apt install libncurses-dev gawk flex bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf git

2) clone the kernel from github and checkout (Rather large, multiple GB's):

* git clone https://github.com/torvalds/linux.git
* cd linux
* git checkout v6.xx

3) load current kernel config and change configuration then run the following scripts/config commands:

* make olddefconfig

4) build the kernel

* make -j 16

But both the v6.8 and v6.9 kernel fail after ~10 to 15min of compiling with this same error:

   make[1]: *** [/home/darin/kernel/linux/Makefile:1919: .] Error 2
   make: *** [Makefile:240: __sub-make] Error 2

I inspected the MakeFile at lines 240 and 1919 but failed to see anything obvious to edit or delete.

Not sure how to proceed from here. I am more than happy to keep trying, but I don't want to waste anyone's time with painful remote troubleshooting.

A side note, I did try patching just for the experience, but the provide patch did not work with either the 6.8 or 6.9 kernel version of exregion.c. However, the patch is clear enough to manually perform the edit and I could manually find the lines that required updatng.
