Linux kernel: delay before power-off

Hi all, for a long time now, I'm seeing unclean shutdowns of SATA drives on different machines running Arch. There is a nice write-up about the problem here: https://lore.kernel.org/lkml/20170410232118.GA4816@khazad-dum.debian.net/ If you are willing to google with the right keywords, you will find a lot of similar reports all over the interwebs. I can remember a configuration setting for the Linux kernel, which existed in ancient times, to delay the final step of powering off the machine for some time. Is there anything like that in the distributed kernels right now? Any knob I could turn? BR
