Commit 17a51f12cfbd ("ahci: only try to use multi-MSI mode if there is more than 1 port") fixed the non-working SATA on a machine with single port and it continues using MSI. Another machine with more ports still uses IO-APIC (was using MSI before 0b9e2988ab22 ("ahci: use pci_alloc_irq_vectors")). Then I applied a478b097474c ("ahci: fix nvec check") but didn't see changes. -- Jarkko
