What does "r8169: can't disable ASPM; OS doesn't have ASPM control" really mean?

I have this message in syslog and dmesg output:

r8169 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control 

Is it a configuration problem or hardware issue?

r8169 is the name of a module for the Realtek RTL8169 Network Interface Controller which may be included in your /etc/modules file. ASPM stands for Active State Power Management. ASPM enablement can be configured by BIOS or by an OS.

To run the aspm test in the Firmware Test Suite (fwts), open the terminal and run:

sudo apt-get install fwts sudo fwts aspm 

To show the verbose results of sudo fwts aspm run the following command:

cat results.log 

This test checks the enablement method in ACPI table and verifies the correctness of the ASPM configuration. Visit the Ubuntu Firmware Test Suite/Reference/aspm wiki for information about how to evaluate the results of running sudo fwts aspm .

I just answered my own Question ... I hope it helps others.

After the above 2 suggested (and these first 2 commands explained and restated for some good definitions and clarity):

I will state how to view the log file easy-peasy

Install: Firmware Test Suite (FWTS) is a test suite that performs sanity checks on firmware. It is intended to identify BIOS, UEFI, ACPI and many other errors and if appropriate it will try to explain the errors and give advice to help workaround or fix firmware bugs.with this command:

sudo apt-get install fwts 

Run the check:

sudo fwts aspm 

And to check the log of this "Check"

cat results.log 

I hope this new bit of info helps other!

I had the same problem at boot and managed to solve following this thread:

$ wget

$ sudo dpkg -i r8168-dkms_8.047.02-1_all.deb

$ sudo rmmod r8169

$ sudo echo "blacklist r8169" > /etc/modprobe.d/blacklist.conf

then reboot.

Hope this helps!
