The PSOD occurs when the port which is used in the LTA session is disabled, while the session is still in progress.
This can occur when the port is changed such as: MTU change; ring size change; queue changes or start/stop of packet captures inside the guest.
This issue is resolved in VMware NSX 3.2.3.1 and 4.1.1, available at VMware downloads.
Workaround:
To avoid this issue, do not make any changes to the port being used in the LTA session, while the session is in progress.
