The PSOD is because of a race between reset and data path. There are two issues here:

Tx queue xmit and completion path ran into a race

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

Identified thanks to these legends in the vmware reddit:

Fixed in later driver release:

Bug Fixes:

———-

– Fixed intermittent TX hang due to race condition between start and stop of TX queue.

– Fixed duplicate nic reset due to race condition between uplink reset and watchdog threads.
