Btw - I just checked 20.10 even using kernel 5.11.8 (latest via "mainline --install 5.11.8" and that current kernel shows the same problem and error message "ERROR Transfer event TRB DMA ptr not part of current TD ep_index 1"
Test hardware: Lenovo Thunderbolt Dock Gen 2" shows these same problems with a high speed USB (Samsung SSD T7) disk on Ubuntu 20.10. No need to involve the gige port to see the problem. This is probably still a bug in the kernel but I'm not sure how you want to report it upstream so it is linked here... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749961 Title: xhci_hcd: TRB DMA errors reported with ASMedia ASM1142 USB 3.1 Controller To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1749961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
