I’m assuming you’ve rebooted host after f/w upgrade since mstflint will report new fw without reboot but card will not use it unless you reboot…
If you still can access HCA with mstflint please get and send me its config/ini file – here is an example: “mstflint -d 83:00.0 dc > myhca.ini”. I’ll see if I can get binary for it.
