As a reminder, so far I don't believe any Dell servers are affected by the corruption issue, even those that have NICs that use the tg3 driver, (though they are affected by the NIC being blacklisted with v6.10.2), if the NICs are the reason for the this problem I haven't found a single example of the IOMMU call traces or any signs of corruption in a Dell, actual issue affects mostly HP servers, about 5 or 6 different models so far, but there's also one IBM/Lenovo, so it's not just HPs, the identical Ubuntu bug report posted above also only mentions HP servers as of now.
