I also experience exactly same issue on multiple USB devices ( USB-WIFI or a USB-Webcam ) only on my brand new AMD Mainboard ( ASRock model: B550M-HDV)
I tried both ubuntu focal and hirsute with latest kernels on my OldPC (ASUSTeK model: M5A78L-M LX3) and on my IntelNUC (NUC8BEB) and this issue does not happen (Tried with same USB-WIFI and USB-Webcam devices). Issue is easily reproducible by inserting USB-WIFI and then executing "ip a" on a shell. -- 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
