Incidentally, just today, I was building upstream kernels manually (for testing some KVM
specific things). I don't build Kernels often. After some trial and error, I ended up with
this sequence:
$ make -j6 && make bzImage && make modules
$ make modules_install && make install
Couple of times Dracut failed to generate correct initramfs, resulting in froze. With a
hint from Haralad Hoyer on IRC, I generated the initramfs manually (usually, using the
host initrd should be sufficient):
$ dracut /boot/initramfs-3.11.0-rc1+.img 3.11.0-rc1+
$ depmod -a

Sure, I can certainly be a user here :-) . Note to self: Still have to debug/bisect an
offending Kernel commit which is causing some KVM unit test failures.
