Pasting the same comment from last time since you missed it:

"No, I don't want any of that crap issuing stuff in dmesg and then people
opening bugs and running around and trying to replace hardware.

We either can handle the error and log a normal record somewhere or we
cannot and explode. The complaining about the FW doesn't bring shit."
