Hi, I have recently bought a USB3-Ethernet adapter, that has RTL8153 chip. I found out that the connection often becomes extremely slow and sometimes, after few hours of usage, it's impossible to suspend or poweroff the machine. I haven't found anything suspicious in logs. When searching the Internet for any clues I've only found that there were problems with autosuspend[1], which is now disabled by default (I've checked with powertop) or some general unsolved issues[2]. While I don't mind that much having to replug the device once in a while, it's really a big issue if I can't suspend the system. Does anyone know where should I report this issue and how to gather more meaningful info? [1] https://askubuntu.com/questions/1044127/usb-ethernet-adapter-realtek-r8153-k...
