[ +0.000002] [drm:radeon_pm_late_init] *ERROR* failed to create device file for power method

But all applications works without any crashes.

some info:

emerge --info
https://bpaste.net/show/8de232451f14

kernel .config:
https://bpaste.net/show/e66311bd3d6e

lspci -v
https://bpaste.net/show/bcea1334468e

What is wrong in my settings?

Before upgrading the kernel all worked perfectly and without any flaws.

There is some suspicion on incorrect command-line options for the Radeon driver.

Code:

cat /proc/cmdline
root=/dev/sda8 raid=noautodetect rootfstype=ext4 pcie_aspm=force asus_laptop.bluetooth_status=0 radeon.dynclks=1 radeon.hw_i2c=1 radeon.no_wb=0 clocksource=hpet


I would be grateful for advice on solving this problem.

Thanks.
