Just changing some kernel options end re-compiling the kernel doesn't
work very well.
Best way is to change the parameters and see if it correctly re-compiles
by executing
build/scripts/build.sh build opt=linux
When the compile runs fine, then you have to change the values in
build/scripts/config/config_linux and start over with a "make mrproper
unpack......"
I quickly checked the kernel config and the support for the Promise
controllers is in there.
Is the BIOS for the controller enable? Is there any quick-boot you could
disable ?
