[PATCH v3] irq_remap: disable IRQ remapping if any IOAPIC lacks an IOMMU

2012-08-08 Thread Seth Forshee
The ACPI tables in the Macbook Air 5,1 define a single IOAPIC with id 2, but the only remapping unit described in the DMAR table matches id 0. Interrupt remapping fails as a result, and the kernel panics with the message "timer doesn't work through Interrupt-remapped IO-APIC." To fix this, check
