Hi Mathias && Balbi and ALL,
We hit one hang issue when using DWC3 XHCI host mode to play Video
for Isochronous transfer.
Both usb-audio module and XHCI driver output errors.
Our kernel version is 3.18.x.
And already include Mathias's commit:
1> xhci: fix off by one error in TRB DMA address boundary check
2> xhci: fix isoc endpoint dequeue from advancing too far on
transaction error
But still can hit this error.
Can anyone give some analysis about this error?
Thanks a lot!
Here is the error log:
