If you connect the 5744 to sil24, does it work? It could be that the nvidia controller is falsely claiming PMP support. Thanks. Oh, you already mentioned that. Can you please post the output of lspci -nn? Probably all that's necessary is to blacklist PMP support on the controller. Interesting.. indeed, the nVidia controller doesn't support port multiplication. If it's that simple, could you attach a patch, instructions to blacklist it, or a link to a commit please? :-)
I tried the following line in drivers/ata/libata-core.c, in ata_device_blacklist, before the final {}, and the issue was not resolved:
{ "nVidia Corporation Device 0584", NULL, ATA_HORKAGE_IPM, },
(also tried "a2" in place of NULL)

cc'd Peer Chen. Hi! It looks like 10de:0584 is lying about PMP support. I'm gonna blacklist this one but if you have better list of devices which are broken, please let me know. Thanks. Created attachment 25444 [details]
ahci-nv-update.patch
Can you please whether this patch fixes the problem?
Thanks.
TJ, Only the MCP89 SATA controller support PMP, you can blacklist other controllers. Do 77 and 79 lie about the support too? right. Looks like it works great.. thanks!

Created attachment 25418 [details] Annotated dmesg with attachments, human device identification, and error output. I have three Venus DS3R Pro enclosures, all of which work fine under FreeBSD. I opted to move them to Linux for better RAID and filesystem support, but was disappointed to find that none of the drives were recognized by the system. The setup is thus: Three Venus DS3R Pro two-drive enclosures, with a Silicon Image SII5744 (SteelVine) controller. four onboard SATA ports, driven by the ahci driver. These ports will not work with the enclosures under Linux. Two ports via PCI Express, sil_ata24. These ports work with the enclosures. Two ports via PCI, sil_ata. These ports also work with the enclosures. (ata1-4) SATA controller: nVidia Corporation Device 0584 (rev a2) Subsystem: Foxconn International, Inc.
