Attached panic screenshot from ESXi console to FreeBSD VM.
I have a screenshot of the panic which I am attaching to this bug report. The environment is FreeBSD Head VM running on ESXi server with vmxnet interface configured.
To recreate the panic
#ifconfig vmx0 media autoselect
vmx0: device enable command failed!
and then shortly there is a panic seen.
Refer the attached screenshot.
Is this fixed by https://cgit.freebsd.org/src/commit/?id=922cf8ac43adc9983f9a9e05cfd838306c1ef483 ?
