http://bugzilla.opensuse.org/show_bug.cgi?id=1178211 Bug ID: 1178211 Summary: IOMMU groups broken on 5.9.1 kernel Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: malcolmlewis@cableone.net QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 843070 --> http://bugzilla.opensuse.org/attachment.cgi?id=843070&action=edit LSPCI information Hi Seems the update to the latest kernel has broken IOMMU groups for qemu machines. I've attached lspci information and IOMMU output with 5.8.15-1-default and 5.9.1-1-default kernels. There are some threads already (eg: https://www.reddit.com/r/VFIO/comments/jhehhl/iommu_groups_broken_on_591_ker...) and seems related to this commit; https://github.com/torvalds/linux/commit/52fbf5bdeeef415b28b8e6cdade1e489279... Is it possible to revert this commit? -- You are receiving this mail because: You are the assignee for the bug.
