Maybe the command line setting is being ignored by your boot loader
and the one built-in to the kernel is being used?

Maybe your kernel is configured to ignore the command line supplied
by your boot loader?

Maybe you're setting it in the kernel build but not realising that
the boot loader passed one is being used instead?

If you provide the kernel configuration and the kernel boot messages
for the last kernel you tried, it may be possible to work out what's
going on.
