I noticed that the ISO I used was a bit old. So I upgraded the system
from source. I now run v5.8.3.33. But that doesn't solve the problem.
But I noticed the problem only occurs since I start Xorg. And I could
notice the following message:
error: [drm:pid-1:csr_load_work_fn] *ERROR* Failed to load DMC firmware
[https://01.org/linuxgraphics/intel-linux-graphics-firmwares], disabling
runtime power management.
I've search for solutions but couldn't find any. I have the following
modules loaded:
$ kldstat

Any idea how to solve that drm error?
Thanks,

Hello,
I am discovering DragonflyBSD v5.8.3 on a ThinkPad X260.
I have read and configure the system according to the documentation I
found on the website and various man pages I read. But the fan keeps
blowing, even when the system is IDLE. And as far as I can tell, the CPU
frequency doesn't seem to go to its minimum value ; which probably leads
to the fan issue.
Here's what I have configured:
$ /boot/loader.conf
acpi_thinkpad_load="YES"
acpi_video_load="YES"
drm_load="YES"
$ /etc/rc.conf
powerd_enable="YES"
#powerd_flags="-u 7 -r 0.2 -T 60"
$ /etc/sysctl.conf
hw.acpi.cpu.cx_lowest=C3
machdep.mwait.CX.idle=AUTODEEP
The CPU is "Intel(R) Core(TM) i5-6300U CPU @ 2.40GHz".
I have attached extracts from sysctl.
I already ran OpenBSD 6.x and FreeBSD 13 on that particular machine and
when idling, then fan becomes silent. So there must be something I do
wrong with my dfly configuration.
Any advices?
Thank you,
Joel
