There is a lot of discussion about this over the past two years. The freedesktop bug was: [drm] HPD interrupt storm detected on connector HDMI-A-1 : switching from hot... https://bugs.freedesktop.org/show_bug.cgi?id=106675 This was supposed resolved in the 4.18 kernel release. However, a search with "interrupt storm switching from hotplug to polling" discloses pages of questions for just about every distribution. A regression is a possibility, other than that, I am no where near familiar enough with hardware to know what would trigger the message, or even if flaky hardware is capable of triggering the problem. -- David C.
