fireb1adex Posted August 14, 2019 Share Posted August 14, 2019 (edited) Hi guys - looking for a bit of advice on how to check what the problem here is. I thought i had a shutdown (the VM I left running looks to have restarted), a quick check in the logs gives me repeated incidences of this message: "Aug 14 09:00:06 FILE-SERVER kernel: nvme 0000:04:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0000 address=0x00000000ffc75000 flags=0x0000]" and mixed in with these are: "Aug 14 09:00:07 FILE-SERVER kernel: amd_iommu_report_page_fault: 1617 callbacks suppressed" I am running new hardware, Ryzen 3900x on Asus x570, and the NVIDIA UNRAID version - the offending hardware is my Crucial NVME SSD running under unassigned devices, it is inside it's own IOMMU group and doesnt share this group with any other devices: "IOMMU group 21:[c0a9:2263] 04:00.0 Non-Volatile memory controller: Micron/Crucial Technology Device 2263 (rev 03)" Looking back I can see this is appearing in the logs since the new installation, but am now at a bit of a loss on what I can do, any advice or guidance would be appreciated!

david279 Posted August 14, 2019 Share Posted August 14, 2019 npt patch was added a long time ago so that won't be it. Have you tried running it without the SSD to see what happens in the log? Quote Link to comment
fireb1adex Posted August 14, 2019 Author Share Posted August 14, 2019 Looks like there is a new BIOS for my board, AGESA 1.0.0.3 Patch ABB that solves PCI/IOMMU issue for some people, might give that a go first and report back (there is no current firmware upgrade for the NVME drive).

fireb1adex Posted September 30, 2019 Author Share Posted September 30, 2019 Ok, well new agesa installed (ABBA), still seeing this issue. The NVME is used solely for 3 Windows VMs and I have notices no issues with running them. Not really sure if this error is anything to worry about or not...the VMs are in a production environment so I need them to remain error free and stable, is there a risk to my machines or their data with this error? Here's what I am seeing at the moment (device 04:00:00 is the NVME drive on its own IOMMU group 21:[c0a9:2263] 04:00.0 Non-Volatile memory controller: Micron/Crucial Technology Device 2263 (rev 03)): Sep 30 13:00:09 FILE-SERVER kernel: amd_iommu_report_page_fault: 1516 callbacks suppressed Sep 30 13:00:09 FILE-SERVER kernel: AMD-Vi: Event logged [IO_PAGE_FAULT device=04:00.0 domain=0x0000 address=0x00000000fe507000 flags=0x0000] Quote Link to comment
