I am now running Ubuntu 20.04 with kernel version 5.4.0-37-generic and have reproduced the bug after running the command # echo "file drivers/pci/* +p" > /sys/kernel/debug/dynamic_debug/control as was requested. Attached is the dmesg log.
Attached to the Thunderbolt hub are an iphone and an external monitor. The connection drops a couple times over the period of the log. ** Attachment added: "dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1853061/+attachment/5384224/+files/dmesg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853061 Title: Connection to USB-C hub frequently drops when charging over it To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1853061/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
