The GPU faults happen whenever the GATT changes, because it translates _every_ address in the GATT through the IOMMU right there and then -- so if parts of the table are uninitialised, they'll cause stray write faults. But no writes are actually _happening_. > I'm going to go ahead on the theory that the BIOS needs an update. I can't really imagine how that would help; how the BIOS would be responsible for this. I'm more inclined to blame the drive. It's not an SSD, is it? -- dwmw2 -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
