Comment # 53 on bug 1119649 from david chang

Hi,

There is a fix from upstream for most realtek chips of this issue.
("b75bb8a5b755 r8169: disable ASPM again") And it was included in kernel
version 5.0.8. So please kindly remove the testing kmp once you have updated to
the latest kernel version. 

I would close this report for now, please reopen if you encounter any problem.
Thanks!
