Title:
Thunderbolt docking station drops USB
Status in linux package in Ubuntu:
Expired
Bug description:
My Lenovo Thunderbolt Dock Gen2 randomly drops the USB controller, resulting
in no USB at all.
It sometimes happens after a few seconds of being plugged in to the notebook,
but sometimes it works for hours.
The display connected to the dock stays active and working.
I tried to blacklist the driver (r8152) for the usb3-ethernet
controller, as suggested in a few forums, but it does not solve the
issue.
dmesg is full of the following messages:
[ 1001.028336] xhci_hcd 0000:08:00.0: WARN Event TRB for slot 11 ep 1 with no
TDs queued?
[ 1001.029304] xhci_hcd 0000:08:00.0: ERROR Transfer event TRB DMA ptr not
part of current TD ep_index 1 comp_code 1
[ 1001.029324] xhci_hcd 0000:08:00.0: Looking for event-dma 000000087785b460
trb-start 000000087785b540 trb-end 000000087785b540 seg-start 000000087785b000
seg-end 000000087785bff0
I'm running ubuntu 20.10, but it also happened under 20.04. Everything is up
to date as of writing this bugreport.
The dock is running the latest firmware, but the issue was present with
earlier version of the firmware too.
I also tried both thunderbolt ports on the notebook (MSI Prestige 15), the
issue happens on both.
The dock works flawlessly under windows 10.
