I updated from 18.04 and run Xubuntu specifically. I updated to 19.04 and my wifi works and everything but for some strange reason for a few weeks now, no matter what I do, I cant get rid of this error.

It pops up in the quick black screen that appears before my login prompt shows up.

No matter what I cannot find anything to fix it, my wifi still works but that error appearing drives me up the wall.

iwlwifi 0000:00:0c.0: BIOS contains WGDS but no WRDS

If you want specifics, there's the whole thing from the logs.
