Hello.

I'm contacting you because your email is listed in www.kernel.org/doc/linux/MAINTAINERS
I encountered a problem with the ahci-mvebu driver. I think it's a bug.

Hardware:
Areca ARC-5040 RAID enclosure (DAS), eSATA port, 8 SATA drive bays with 1x 500GB HDD stand-alone and 7x 2TB HDDs in RAID5.
Linksys WRT-1900ACS v2 router, Marvell Armada 385 (88F6820), one eSATAp using ahci-mvebu driver with port-multiplier support.
The router runs OpenWrt with kernel version 5.15.

Problem encountered:
Areca DAS is not detected properly. When I connect it, I get these repeating errors in kernel log:

[--- from boot log ---]

<6>[  780.275979] ata2: SATA link down (SStatus 100 SControl 300)

The same errors appear if I leave it connected during reboot.
I tried to limit SATA speed to 150 and to disable NCQ from Areca admin interface. It didn't work.
I found no way of making it work.

The same router works perfectly when I connect a laptop HDD.
The same DAS, including the same eSATA cable, works perfectly when connected to an older 
Linksys WRT-1900AC v1 with Marvell Armada XP (MV78230), using sata-mv driver. 
This is the kernel log from the older router:

I'm not currently using the new router, so it's available for tests.
Thanks.
