iommu=soft appears to have fixed the corruption on one system, but another is still having problems. The key difference between the fixed and broken systems is that the broken system has its root filesystem on a linux (md) raid1 disk pair.
I installed a single extra drive in the broken system and ran tests using md5sum with iommu=soft, and no corruption appeared. So apparently the broken system was suffering from the iommu issue as well. I'm unsure whether to keep this bug report open, or file a new report? I could also use some advice on potential workarounds or ways to better isolate the problem. -- opteron amd64 data corruption https://bugs.launchpad.net/bugs/129260 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
