I don't recall any boot-time ACPI interrupt configuration changes recently, so I wouldn't be surprised if you get the same behaviour back several kernel versions.
if it comes up in IOAPIC mode when "acpi=off", then that would be a clue -- but it seems that recent systems don't include MPS, and thus when ACPI is off, so it IOAPIC.
That said, it should also boot with ACPI in "noapic" mode, and if it doesn't, then that could indicate an ACPI-specific issue that may carry over into ACPI+ioapic mode.
