Has anyone:
Successfully downloaded the kernel source?
Successfully installed a built kernel without it crashing on startup?
For Ubuntu 18.04.1?
I managed to use synaptic to get
linux-source version 4.15.0.36.39
linux-source-4.15.0 version 4.15.0.36.39
I copied the tarball linux-source-4.15.0.tar.bz2
to my home directory.
Unzipped it and made it using (after installing libncurses)
make menuconfig
copy .config to .config.bak
make mrproper
copy .config.bak to .config
make dep
make clean
make bzImage
make modules
make modules_install
make install
The kernel builds but after reset it tries to boot kernel 4.15.8 and fails because it cannot find a memory target.
Using the alternative method of downloading source apt-get source linux-image-$(uname -r)
fails for this reason
As someone who maintains a driver 18.04.1 is a useless release thus far.
