Possibly missing firmware for module: wd719x
git clone https://aur.archlinux.org/aic94xx-firmware.git
cd aic94xx-firmware
makepkg -sri
git clone https://aur.archlinux.org/wd719x-firmware.git
cd wd719x-firmware
makepkg -sri
and then mkinitcpio -p linux
again.
@codydg Obviously you read nothing about those specific warnings above.
You "might" need those old SAS/SCSI Disk Controllers firmwares if you plan to use an old server.
The inevitable "Warnings" are there for the rest of us.
You like risking something not working in your system?
Sure, go ahead, install the firmwares, just to justify your OCD.
