https://bugzilla.kernel.org/show_bug.cgi?id=207887 --- Comment #2 from Marco Trevisan (Treviño) (mail@xxxxxxxxx) --- Not sure if this is totally related to the dock or more likely to an USB mechanical keyboard (both TEX Yoda II and TEX Shinobi - this one is also bluetooth when connected) that seems to behave differently. This is on kernel 5.4.0-42-generic (ubuntu) In the middle of using it I've got a: set 01 18:35:44 tricky kernel: usb 1-3.2.3: reset full-speed USB device number 33 using xhci_hcd set 01 18:36:11 tricky acpid[2940]: input device has been disconnected, fd 28 set 01 18:36:11 tricky acpid[2940]: input device has been disconnected, fd 29 set 01 18:36:13 tricky kernel: Bluetooth: hci0: advertising data len corrected set 01 18:36:16 tricky kernel: input: TEX-BLE-KB-1 Mouse as /devices/virtual/misc/uhid/0005:0000:0000.0038/input/input108 set 01 18:36:16 tricky kernel: input: TEX-BLE-KB-1 Keyboard as /devices/virtual/misc/uhid/0005:0000:0000.0038/input/input109 set 01 18:36:16 tricky kernel: input: TEX-BLE-KB-1 Consumer Control as /devices/virtual/misc/uhid/0005:0000:0000.0038/input/input110 set 01 18:36:16 tricky kernel: hid-generic 0005:0000:0000.0038: input,hidraw4: BLUETOOTH HID v0.00 Mouse [TEX-BLE-KB-1] on 44:85:00:64:22:b9 set 01 18:36:16 tricky systemd-logind[3018]: Watching system buttons on /dev/input/event26 (TEX-BLE-KB-1 Keyboard) set 01 18:38:11 tricky kernel: INFO: task kworker/u16:8:183192 blocked for more than 120 seconds. set 01 18:38:11 tricky kernel: Tainted: G C OE K 5.4.0-42-generic #46-Ubuntu set 01 18:38:11 tricky kernel: "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. set 01 18:38:11 tricky kernel: kworker/u16:8 D 0 183192 2 0x80004000 set 01 18:38:11 tricky kernel: Workqueue: scsi_tmf_4 scmd_eh_abort_handler set 01 18:38:11 tricky kernel: Call Trace: set 01 18:38:11 tricky kernel: __schedule+0x2e3/0x740 set 01 18:38:11 tricky kernel: schedule+0x42/0xb0 set 01 18:38:11 tricky kernel: schedule_timeout+0x203/0x2f0 set 01 18:38:11 tricky kernel: wait_for_completion+0xb1/0x120 set 01 18:38:11 tricky kernel: ? wake_up_q+0x70/0x70 set 01 18:38:11 tricky kernel: command_abort+0x60/0xa0 [usb_storage] set 01 18:38:11 tricky kernel: scmd_eh_abort_handler+0x8d/0x220 set 01 18:38:11 tricky kernel: process_one_work+0x1eb/0x3b0 set 01 18:38:11 tricky kernel: worker_thread+0x4d/0x400 set 01 18:38:11 tricky kernel: kthread+0x104/0x140 set 01 18:38:11 tricky kernel: ? process_one_work+0x3b0/0x3b0 set 01 18:38:11 tricky kernel: ? kthread_park+0x90/0x90 ... repeated various times ...
