--- Comment #7 from Marc Thomas marc@dragonfly.plus.com --- I also see the WARNING messages in 4.17.10 and 4.18-rc6:

This is on an Ryzen 2700x based system with an RX480 GPU, connected to an IIyama ProLite XB2380HS via DVI.
I'm also running Slackware-current Linux, so I wonder whether it's something in Slackware's kernel config.
PS: This may be the same as Bug 106164.
