I think for your system you will need to change module "mpt3sas" to "mptsas" and/or "mptbase". After adding config file you will have to also update initramfs with: $ sudo update-initramfs -u I didn't tested this suggestion and you might break your system, so be prepared to boot from livecd to rollback changes, but because your root filesystem is on other disks I think it should be ok and hopefully your system will boot normally. There is also a possibility that "softdep" feature of kmod is not yet implemented on your old system and this suggestion won't work. -- With kindest regards, Alexander. ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ Debian - The universal operating system ⢿⡄⠘⠷⠚⠋⠀ https://www.debian.org ⠈⠳⣄⠀⠀⠀⠀
