http://bugzilla.opensuse.org/show_bug.cgi?id=1048348 Bug ID: 1048348 Summary: AMD-Vi freeze when iommu is on with kernel > 4.4.72 Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.3 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: bruno@ioda-net.ch QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 732108 --> http://bugzilla.opensuse.org/attachment.cgi?id=732108&action=edit HWInfo output Motherboard is a ASUS CROSSHAIR V FORMULA-Z, BIOS 2201 03/23/2015 (latest available) The CPU is an AMD FX(tm)-8350 Eight-Core Processor With 4.4.72 everything was working (since years the hardware was used before with 13.1 and 42.1), even with the nvidia blob ;-) Since kernel 4.4.74 with iommu enabled in bios, I got freeze, like one of the trace I finally found in journal. (Attached) Today I retry with 4.4.75 and get immediately after the system is online a AMD-Vi buffer timeout error. I since then disabled iommu in the bios and the computer doesn't show bugs. (But as the computer should run VM iommu is quite mandatory) I know there was a kernel-firmware and ucode-amd update between the 4.4.72 and now. -- You are receiving this mail because: You are on the CC list for the bug.

Since then I've rebooted there's no evidence of crash, which is good. I'm doing heavy testing with vm and heavy load on io to make sure iommu can resist. I'm still seeing now AMD-Vi: Command buffer timeout (even before the vm was loaded) I don't know if they are important or not.

After working a bit with any vm (tumbleweed zypper dup) it crash and hangs worstly than with nvidia. Hope this will give you more clues about what happening.

Please try KOTD (kernel-of-the-day) built from the latest git tree instead: http://download.opensuse.org/repositories/Kernel:/openSUSE-42.3/standard/

This is basically the would-be-next-update kernel.

Ok, now one of the machines runs with "4.4.79-3.gb9215e3-default". IOMMU is re-enabled again. Reports will follow. -- You are receiving this mail because: You are on the CC list for the bug.
