Thanks for the heads-up.

Unfortunately the PCIe is slot already occupied, so that's why I
searched for and found the Mini PCIe Sil3132 card.

Legacy IRQ routing on PCIe is broken in what sense? Software (device
tree, kernel) or silicon (p2020) ?

On the MSI side, I'm getting quite far on transfers, but at one point
the device stalls. Maybe a race condition in interrupt handling in
sata_sil24.c?
