--- Comment #3 from Mark Johnston <markj@FreeBSD.org> ---
Created attachment 205876

proposed patch

Based on the line numbers, vmxnet3_isc_txd_credits_update() is being reente=
red.
 I think there is a window where vxcr_next is an invalid queue index; if we
take an interrupt during that window, we may reference invalid memory.

Please try the attached patch, which attempts to bandage the problem.
