Unraid OS 6.10.3 Now Available

The primary purpose of this release is to address an issue seen with some HP Microserver Gen8/9 servers (and other platforms) where data corruption could occur if Intel VT-d is enabled. ALL USERS are encouraged to update.

While we have not identified the exact kernel commit that introduced this issue, we have identified a solution that involves changing the default IOMMU operational mode in the Linux kernel from “DMA Translation” to “Pass-through” (equivalent to the “intel_iommu=pt ” kernel option).

At first, we thought the ‘tg3’ network driver was the culprit. However, upon thorough investigation, we think this is coincidental and we have also removed code that “blacklists” the tg3 driver.
