            Bug ID: 247676
           Summary: nvme not detected when hot-adding new ebs to aws
                    instance
           Product: Base System
           Version: 12.1-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs at FreeBSD.org
          Reporter: freebsd at darkain.com

On AWS, when hot adding an EBS volume to an EC2 instance, FreeBSD doesn't
auto-detect the hot-add event.

Manually running "devctl rescan pci0" will detect the newly added device.

Rebooting the instance (which also forces a pci rescan at boot) will also work.
