Adding the kernel track to this bug after checking with Michael (IBM). Although the bug was found in a flavor kernel of Ubuntu, it sounds like (from the notes in the description) that this might a generic issue with 18.04.3 and newer kernels.
The next steps for IBM is to reproduce this issue on 18.04.3 or newer released kernel. Also, compare with the upstream kernel to see if issue was already fixed. You could use the mainline builds to compare https://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ ** Changed in: libvirt (Ubuntu) Status: Triaged => Invalid ** Changed in: ubuntu-power-systems Assignee: Canonical Server Team (canonical-server) => Canonical Kernel Team (canonical-kernel-team) ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Canonical Kernel Team (canonical-kernel-team) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846237 Title: Kernel Panic while virsh dump of Guest with 300G RAM is triggered.
