If I connect the dock before boot, it will work correctly. However, if a connect/disconnect it after boot it won't be recognize and will lead soon after to system crash. The gnome icons start to disappear and when using commands on terminal input/output failure errors appear. I found another bug which seems related to mine, but in my case it leads to system crash: https://bugzilla.kernel.org/show_bug.cgi?id=206459. I am encountering another problem with USB-C drive on thunderbolt3 ports working if connected before boot and not otherwise. But without leading to system crash: https://bugzilla.kernel.org/show_bug.cgi?id=206649 I joined dmesg where disconnection starts at time 185 with some errors occuring just after like: [ 184.038519] usb usb6: USB disconnect, device number 1 [ 184.038523] usb 6-3: USB disconnect, device number 2 [ 184.167256] usb 5-4: Not enough bandwidth for altsetting 1 [ 184.167260] usb 5-4: 1:1: usb_set_interface failed (-19) Also the journalctl shows some errors: fév 23 17:55:06 pc-de-user kernel: usb usb6: USB disconnect, device number 1 fév 23 17:55:06 pc-de-user kernel: usb 6-3: USB disconnect, device number 2 fév 23 17:55:06 pc-de-user kernel: usb 5-4: Not enough bandwidth for altsetting 1 fév 23 17:55:06 pc-de-user kernel: usb 5-4: 1:1: usb_set_interface failed (-19) Then the system crashes showing "input/output failures" just by using some commands like "ls" or "cat". -- You are receiving this mail because: You are watching the assignee of the bug. ----- End forwarded message -----
