[Bug 1171289] New: Kernel 5.6+ breaks KVM passthrough
http://bugzilla.opensuse.org/show_bug.cgi?id=1171289 Bug ID: 1171289 Summary: Kernel 5.6+ breaks KVM passthrough Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Factory Status: NEW Severity: Major Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: k6demello28@fastmail.fm QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 837477 --> http://bugzilla.opensuse.org/attachment.cgi?id=837477&action=edit stack trace generated while starting vm with passthrough I am having the problem outlined in the kernel bugzilla (207489), where pci passthrough with KVM on intel is causing a kernel panic. I have attached the stack trace produced with 5.6.11, but it is identical with all versions of the 5.6 kernel that I have tested so far. https://bugzilla.kernel.org/show_bug.cgi?id=207489 There is a patch provided in the kernel bug that solves the issue. Can this patch be included in the openSUSE kernel for versions 5.6+ that are included in tumbleweed? -- You are receiving this mail because: You are on the CC list for the bug.

This also fixes the issue. Can this be pulled into the default kernel instead of the original patch? -- You are receiving this mail because: You are on the CC list for the bug.
