Thanks.
I have tried unloading bunch of modules to identify when power
management is disabled. And it happens exactly when loading when I issue
"kldload i915".

I can't use modesetting without i915.ko ; because /dev/dri/card0 is
created by that particular module. So using acceleration glamor or none
can't be done without first loading i915. Or maybe I missed something?
I have also installed devfw-i915. And the firmware file is available at
/usr/local/share/fw-i915/i915/skl_dmc_ver1_26.bin
I've read the files from DPorts/sysutils/devfw-i915/ and even rerun the
regen-firmware.sh as described in pkg-install.fw.
Maybe that binary file should be copied somewhere else on the
filesystem? But I have no clue where.
Thanks,
Joel

If it is GPU related we just might not have a working solution to the
power management. You could try adjusting the Xorg configuration to use
the "modesetting" driver with acceleration disabled but it's a
long-shot. It kinda feels like the GPU is defaulting to a consumption
mode that is forcing the fans to run.
