Hi, Sorry if someone gets this twice. My first version didn't go to the list.

I have same problem on my Dell Optiplex 990 (running in "headless" mode, no monitor attached!). After upgrade from 6.5-stable to 6.6-current, CPU temperature increased from 50C to 70C..80C and the fans are running at full speed. So, I went and cloned OpenBSD src tree from https://github.com/openbsd/src/ Then I started bisecting kernel commits from 6.5-release to 6.6-current: > ls -1 kernels bsd.apr10.a72c25aac8e43fe bsd.apr14.505701c75b30a46033a8 bsd.apr23.53d03815630664 bsd.apr27.c1f77a6b17d5a799d322 bsd.apr29.47170b90f4a74 bsd.apr5.b2516e1f98d4a5f7757 bsd.jul31.ddc1a6c2c17 bsd.jun.b2a28ec4ea bsd.jun1.535cf6c2b bsd.may1.4a0e86bfb04cce9 bsd.may19.01b2b04ad452620a32 > (Note the list isn't complete. I noticed that kernel became backwards incompatible at some point in April and I had to create a temporary 6.5 installation on another disk.) Eventually I pinned the problem down to April 14/15: FAULTY 091f8f6587f dlg Mon Apr 15 02:59:41 2019 +0000 the myx_cmd FAULTY 1bbcb699ab8 dlg Mon Apr 15 00:28:29 2019 +0000 there's a bunch PROBLEM! 7f4dd37977d jsg Sun Apr 14 10:14:50 2019 +0000 Update shared drm code OK 505701c75b3 visa Sun Apr 14 08:51:31 2019 +0000 Add lock I must admit that I don't have yet any idea how to fix the problematic commit (or what is actually wrong there). Reverting 7f4dd37977d didn't work for latest 6.6-current as there have been too many changes after that. I also tried to check the latest changes from linux-4.19.y, but didn't spot anything useful.
