https://bugzilla.kernel.org/show_bug.cgi?id=207887 Bug ID: 207887 Summary: USB devices connected to Thinkpad Dock hangs after a while Product: Drivers Version: 2.5 Kernel Version: 5.0.0 -> master Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: USB Assignee: drivers_usb@xxxxxxxxxxxxxxxxxxxxxx Reporter: mail@xxxxxxxxx Regression: No Created attachment 289275 --> https://bugzilla.kernel.org/attachment.cgi?id=289275&action=edit DMesg of the hang with kernel-5.4.26-050426 Since I've moved from kernel 4.15 to kernel 5, the USB hub managed of my Thinkpad Dock doesn't seem to work well after some usage (unfortunately is quite hard to find a reproducer, as it "just happens", normally while writing). This seems to be mostly triggered by the usage of an USB keyboard, as when the USB traffic is limited to other devices, it doesn't seem to happen.
