Comment 25 for bug 1667750

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.
