Hello,
Has this always behaved like this or did it start occurring after changing driver/firmware?
When vmkernel says "Hardware failure" for something it generally indicates a firmware issue (or less often, an actual physically failing device).
If you are not on latest firmware, updating to that (and matching driver) would likely be the best place to start.
Unsure if possibly related in any way but seeing a few bits online relating to issues with firmware on these cards:
