Hello,

i installed an new gentoo to my server system:
Linux 3.18.9-gentoo #2 SMP Thu Apr 2 19:44:03 CEST 2015 x86_64 Intel(R) Xeon(R) CPU E5320 @ 1.86GHz GenuineIntel GNU/Linux

The PC does have many sata pata controller. For all of them i choose the kernel module to build in the kernel.
with DMESG You can see:
ahci
ata_piix
sata_via

i installed the system to an ide drive while no other hard disk where connected. Everything work fine.
Then i connect hard disk to the sata_via controller. The system still works.
But when i connect hard disk to the ahci controller. i get kernel panic.
I think its because the new disk on the ahci controller gets the /dev/sda.

How can i change the order for the kernel modules?

i like to have the order "ata_piix sata_via ahci"

i used google but found no solutions that works (i have tryed many udev sample)

Can someone tell me how that works or give me a link to the docu how kernel modules are loaded in the newest gentoo version.

Or some other way to put every single hard disk to a permanent /dev/sd* link

best regards
