Bug ID: 1047162
Summary: kernel oops kvm-qemu: free_pipe_info
Classification: openSUSE
Product: openSUSE Distribution
Version: Leap 42.2
Hardware: Other
OS: Other
Status: NEW
Severity: Normal
Priority: P5 - None
Component: Kernel
Assignee: kernel-maintainers@xxxxxxxxxxxxxxxxxxxxxx
Reporter: jjm@xxxxxxxxxx

Found By: ---
Blocker: ---

I'm running docker inside a VM with kvm-qemu with libvirt and this oops happens
randomly when the VM has some load.

It sometimes happens on zypper install; not in this example.

The VM:

The host:
