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