Not running any VMs but I did have SR-IOV and VT-X enabled in the BIOS. Server has a HP B120i which is a fakeraid device and the drives are accessed as simple AHCI devices. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1970453 Title: DMAR: ERROR: DMA PTE for vPFN 0x7bf32 already set Status in linux package in Ubuntu: Confirmed Bug description: I'm running Ubuntu 22.04 with kernel 5.15.0.27.30 on an HPE ProLiant DL20 Gen9 server.

[Kernel-packages] [Bug 1970453] Re: DMAR: ERROR: DMA PTE for vPFN 0x7bf32 already set
I hit this bug upgrading my home server (proliant microserver gen9) and it seems to be causing memory corruption when it occurs ( at least in combination with zfs ). Using zfs mirrored root I experienced this issue after only a few minutes uptime, with DMAR messages flooding the log and very high CPU usage. After rebooting with intel_iommu=off things are back to normal, but a zfs scrub indicated several thousand checksum errors detected on the root volume, some of them unrecoverable that had to be restored from backup, and a separate zfs RAIDZ1 volume experienced corrupted metadata and had to be rolled back with some data loss. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1970453 Title: DMAR: ERROR: DMA PTE for vPFN 0x7bf32 already set Status in linux package in Ubuntu: Confirmed Bug description: I'm running Ubuntu 22.04 with kernel 5.15.0.27.30 on an HPE ProLiant DL20 Gen9 server.
