Vmware KB:<\/b><\/p>

https:\/\/kb.vmware.com\/s\/article\/67686<\/a><\/p>

The PSOD is because of a race between reset and data path. There are two issues here:<\/p>

Tx queue xmit and completion path ran into a race<\/p>

The above race caused queue stuck and uplink reset, which ran into the PSOD.

Fixed in later driver release:<\/b><\/p>

Bug Fixes:<\/p>

———-<\/p>

– Fixed intermittent TX hang due to race condition between start and stop of TX queue.<\/p>

– Fixed duplicate nic reset due to race condition between uplink reset and watchdog threads.<\/p>
