intel dynamic platform and thermal framework pnp fatal

The laptop screen usually flickers blank and then back on when there are changes in video configiration. Connecting HDMI -> HDMI with intermediate HDMI -> DVI + DVI -> HDMI does make this problem. NOTE: Connecting to this same TV-monitor-combos via a HDMI -> DVI-adapter to their DVI-port does not make this problem. Two TV-monitor-combinations (a unknown Telefunken one, and a Samsung P2470HD) via HDMI were problematic to me, whereas a Dasiung Paperlike HD-FT (also HDMI interface) was not. I cannot see any kernel messages since all displays are blank.Ĭompiling a kernel with HDMI-CEC disabled does not help. If there is a kernel panic I cannot see because my system has no numlock, capslock or scrollock-LEDs.

SysRq still works, even if I plug in a USB-keyboard (drivers already in the kernel) after the fact.

The laptop is frozen then: Userspace seems not able to run anymore, as I can see that my predefined ACPI-keys do not work (suspend, change display brightness (which I would notice) (yes!, I do that via ACPI-buttons), poweroff). When the laptop is on, when I activate a problematic and connected HDMI-display via xrandr or by switching from xorg to virtual console, the laptop-screen goes blank, and the external display receives physical signal (it reports a video mode) but stays blank too. With two Television-Monitor-Combos I recently had the following: Probably similar issue here I cannot see the kernel output since both displays go blank:
