I'm also experiencing the same issue with the ASM1142 controller on the Core X Chroma and can reproduce consistently. I'm running kernel 5.0.9.
Guilherme, thanks for your work diagnosing this. This device is sold by Razer. I will try and reach out but they do not claim Linux support on any of their devices so I worry this may go unfixed. Barring a firmware fix, is there any hope of this being fixed with a quirk, as the other controller was? I realize this LP is not the ideal place for such a fix to take place, but I am happy to participate in finding a solution. -- 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/ubuntu/+source/linux/+bug/1749961/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
