I'm pretty sure I tried the pata_marvell driver with some older kernels last year and had no positive results, but I do not remember in detail.

Swapping the drives slots does not change anything. ST3250310NS works, ST3500418AS not.
For my ST3250310NS, "hdparm -I" shows "Gen1 signaling speed (1.5Gb/s)" only. That's why I call it a SATA-1 drive. Oddly enough, a web search shows that it is sold as Sata-2 (https://www.seagate.com/docs/pdf/datasheet/disc/ds_barracuda_es.pdf).
I double checked with a FUJITSU MHZ2160BH laptop drive (hdparm shows Gen1=1.5Gb/s only), this works without problems. Other Gen2/Gen3 drives e.g. a WD3202ABYS or WD30EFRX do not work ("failed to IDENTIFY").
I may need to summarize my observations more precisely: drives that advertise a speed higher than Gen1=1.5Gb/s ("hdparm -I") do not work with the 88SE6121 controller and Linux kernel ahci module. Limiting SATA speed (libata.force=1.5G ...) does not help.
I can't completely rule out that the problem is definitely something to do with the SATA speed. These are just the observations with the drives available to me.
