https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231070 Bug ID: 231070 Summary: Crash in nvme_qpair_reset() on base/head r338418 on VirtualBox 5.2.18 Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: Trond.Endrestol@ximalas.info Host is VirtualBox 5.2.18, Windows 7 x64 SP1, and Intel Core i7 960 @ 3.2 G= Hz. Guest is amd64 base/head r338418. Last known good revision is r338206. This can so easily be a bug in the VirtualBox implementation as it can be a= bug in the FreeBSD implementation. The NVMe controller isn't critical to me, so I removed it from the VM, edit= ed /etc/fstab, and carried on.
