I have the same problem with my USB 3.1 controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller.
I passthru the controller to XEN VM. I then connect to it USB TV Tuner card. I am using VDR software which is TV software that when not in use is scanning for new channels. Sometimes after few hours, sometimes after few days it crashes with following error: [131382.068144] xhci_hcd 0000:00:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 0 comp_code 3 [131382.068182] xhci_hcd 0000:00:00.0: Looking for event-dma 0000000210196600 trb-start 0000000210196740 trb-end 0000000210196760 seg-start 0000000210196000 seg-end 0000000210196ff0 Then same problem is not present with the onboard USB 3.0 controller. If I passhtru it to the XEN VM it working without any problems. So this must be some problem with USB 3.1 driver (not 3.0) or ASMedia firmware. I can provide whatever information is necessary to fix this bug. I can provide shell account to my VM also if somebody wants to debug it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667750 Title: xhci_hcd: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1667750/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
