[Bug 1832472] Re: cdc_ncm floods syslog unneccessarily
Chrome OS also can't support RTL8156 until this is fixed. Every kernel version Chrome OS uses spams /var/log/syslog with ~30 messages/second (~200MB/day or ~1GB/week). We can not use the Realtek "proprietary" (though open source) driver. Realtek needs to look at this and I've contacted Realtek directly about this. I can't determine what is triggering the repeated link status messages from USB CDC specs. From what I understand in the spec, USB_CDC_NOTIFY_SPEED_CHANGE and USB_CDC_NOTIFY_NETWORK_CONNECTION (in that order) messages should only be sent once after device is enumerated and again when link state actually changes. This is in fact how cdc_ether devices behave using the same messages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832472 Title: cdc_ncm floods syslog unneccessarily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1832472/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is there a way for a normal user to fix the log spamming? I bought a RTL8156 based USB adapter but it's making the journal unusable. It is adding 30+ kernel messages per second and consuming pointless io / cpu cycles (system-journald, i.e. 5% permanent cpu usage on my Pi4). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832472 Title: cdc_ncm floods syslog unneccessarily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1832472/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1832472] Re: cdc_ncm floods syslog unneccessarily
I was mistaken, the TRENDnet TUC-ET2G is actually based on RTL8156 while the TUC-ET5G is effectively based on Aquantia IC. I made wrong assumption since Aquantia also has a USB3.0 to ETH 2.5Gbe bridge. Anyhow, so I tested with RTL8156 driver you linked (which actually is part of RTL8152 driver) under Ubuntu 18.04.2. I had to tweaked driver to support TUC-ET2G by adding the idVendor and idProduct of the device. Could have used a modprobe conf file instead of tweaking the code. Now the device works well without flooding anymore the logs ! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832472 Title: cdc_ncm floods syslog unneccessarily To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1832472/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
