As others have said make sure that the initramfs has been updated with
this blacklist directive as well.

On Debian-esque distributions such as Ubuntu the following incantation
will do that:

sudo update-initramfs -u -k all

Then reboot.

The point is that modules can get loaded early during the boot process,
before the root filesystem has been loaded. Those modules are packaged
up into a compressed file called the initramfs (initial RAM filesystem)
which gets loaded into memory just after the kernel does. It contains
early initialisation code to bring the system to the point where it can
mount the root fs and then pivots to it. The update-initramfs script
propagates your runtime configuration into the initramfs.
