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
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:
