Hi Alessandro,

The easiest way to check is by searching for "ASM1166" in the AHCI kernel driver. You can do this on the GitHub repository for the Linux kernel: https://github.com/torvalds/linux/blob/master/drivers/ata/ahci.c. I found that the driver does indeed support ASM1166.

I couldn't locate the exact patch that introduced this change in the kernel source. However, there's a good chance that it is supported in the latest releases, as people have been discussing it on the internet.

Regarding recommendations and stability, I came across a related thread that might interest you. They mention firmware updates as well: https://forum.openmediavault.org/index.php?thread/46589-unexpected-disk-errors-seen-with-pcie-card-when-adding-more-than-2-disks/.

I hope this helps!

p.s. if you need that, I can double-check our kernel sources tomorrow for you.

Pawel
