Force disable of ata device at boot

Hello,
First, sorry in advance, this may not be purely nix related but maybe someone here will have a solution for me.

I have a PCIE raid extension card that seems to be badly supported by linux, and it is extending my boot time by about 90 sec.

After investigations in the boot logs, it seems that 2 ata devices are faulty and fails to identify after 5, 10 and 30 seconds for each of them.

I do not need the disks connected to the extension card, so I decided to disable the faulty ata devices at boot time by adding boot.kernelParams = ["libata.force=8:disable,3:disable"]; to my configuration.

It seems to have disabled the ata8 device, but ata3 device still timeout during boot, adding 45 sec of hang to the boot time.

No matter what I tried, I can’t disable ata3 device, I tried to only have libata.force=3:disable, but the ata3 is still active at boot.

Any idea of something that could cause that ?
