The original lspci -vvv output I posted was from the time I had
Firewire disabled in BIOS, I guess I've reset settings since then
because I was trying on different BIOS versions. With Firewire enabled
at 06:00.0 is Firewire controller instead of SATA controller, at
07:00.0 is SATA controller and at 07:00.1 is IDE interface.

So I guess boot always fail on the 07:00.1 (or 06:00.1) IDE interface:
JMicron Technology Corp. JMB361 AHCI/IDE (rev 02) (prog-if 85 [Master
SecO PriO]).

If I disable Firewire boot fails with:
(XEN) PCI add device 0000:00:18.4
(XEN) PCI add device 0000:06:00.0
(XEN) Xen BUG at pci_amd_iommu.c:35

If I enable Firewire boot fails with:
