Hector Martin 188775181b firewire-ohci: work around oversized DMA reads on JMicron controllers ... At least some JMicron controllers issue buggy oversized DMA reads when fetching context descriptors, always fetching 0x20 bytes at once for descriptors which are only 0x10 bytes long. This is often harmless, but can cause page faults on modern systems with IOMMUs: DMAR: [DMA Read] Request device [05:00.0] fault addr fff56000 [fault reason 06] PTE Read access is not set firewire_ohci 0000:05:00.0: DMA context IT0 has stopped, error code: evt_descriptor_read This works around the problem by always leaving 0x10 padding bytes at the end of descriptor buffer pages, which should be harmless to do unconditionally for controllers in case others have the same behavior.
