With 6.1-RC of today I have the same sympthoms as with 5.4-RELEASE
1) machine suffers from ATA timeouts if ACPI is fully enabled;
2) debug.acpi.disable="pci_link" in /boot/loader.conf eliminates the problem.
So, Soren seems to be right: this is interrupt routing problem
and not ATA problem.
The question is: should I consider the workaround mentioned above as solution?
What will I miss if I keep debug.acpi.disable="pci_link" forever?
