Booting with a mainline kernel on Ubuntu with 4.7.5 or above.

Some machines die with "cannot find root" unless CONFIG_UEVENT_HELPER is set. This is the case with Ubuntu kernels 4.6.x and earlier, but not in 4.7.5. I have no idea why.

Here's how I built my own:

• git clone --branch v4.7.5 --depth=1 git://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/mainline-crack
• Later: git fetch --depth=1 origin v4.8.8; git checkout FETCH_HEAD; git checkout -b v4.8.8-pjf
• rm -rf debian.master debian
• Apply all the patches from mainline with -p1 ( http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.5/ )
