The "Tx timeout" message in the log is gone, but the NIC connection still dies after random period of time while I don't use the laptop. There was another commit that got my attention which disables LPM on the realtek usb hub on WD19: https://github.com/openSUSE/kernel/commit/e9b5c04bc3943ccdb0353d4d0f31e329ae... So guided by that I found out that my rtl8153 has as parent a SMSC USB5537B usb hub (0424:5537). Just as a lucky shot I added kernel parameters usbcore.quirks=0424:5537:k But it didn't have effect I would be happy to test quirks or provide logs. -- You are receiving this mail because: You are on the CC list for the bug.
