Looks like you attached the wrong file.  Please attach your full dmesg output.

Err. Sorry about that.
I've uploaded the correct file now.

An interesting information: It's only with open source amdgpu driver. With amdgpu-pro it's not happening but this driver isn't compatible with Ubuntu 17.10.

I've got a similar issue on a recently purchased Dell Inspiron 5770 with an AMD Radeon 530 graphics card with openSUSE Tumbleweed.

Reboot or attempt to switch to text console causes a hang and /var/log/messages contains the above message + kernel bug with a stack trace. Full details are here:

https://bugzilla.opensuse.org/show_bug.cgi?id=1068793

vkrevs@yahoo.com, 

Are you using TLP or something similar?

I ran some tests and found that's only happening when using TLP. Tried with Ubuntu 17.10 and Fedora 27, same results.

Looks like TLP was installed on my laptop at initial installation time.

rpm -qa  | grep -i tlp
tlp-1.0-1.2.noarch
tlp-rdw-1.0-1.2.noarch


The latest openSUSE Tumbleed snapshot switched to 4.14 kernel - I got the same issue with that too on first boot. The bug report in openSUSE's bugzilla contains the /var/log/messages for that first boot with 4.14.

OTOH, TLP services are not enabled according to tlp-stat -s, so does that mean my laptop is not using TLP after all?

These systemd services are not running but according to tlp-stat, it's enabled.
Can you try to uninstall these packages and see if the error persists?

In my laptop, the problem is only happening when I install/enable them. Is it a power management bug?

Uninstalling tlp and tlp-rdw packages eliminates the error. 

What I don't get is that runtime pm for amggpu driver is supposed to be disabled by default according to TLP docs.

I'll try reinstalling TLP and follow the TLP troubleshooting guide to see exactly what setting is causing this.

Hey, 

Is your system using 'pcieport' module?

I've added it to RUNTIME_PM_DRIVER_BLACKLIST in TLP's configuration and now the problem is fixed!

Not sure why it's happening in Linux 4.13+ and not in 4.4 with AMDGPU-Pro installed.

Hi Rene,

Sorry for the delay in responding. Thanks for your suggestion regarding the pcieport module. Adding it to RUNTIME_PM_DRIVER_BLACKLIST does fix the problem while TLP is installed.
