Hello Mathias,
Hi
Can you please confirm of the erratic behavior we've discussed so far, on this
thread ?
It'd help to know if it really is a bug or something else.
Could you add xhci debugging?. The current logs mainly show usb core
reporting errors on urbs returned (or timeout) from xhci.
xhci debugging can be added with
echo -n 'module xhci_hcd =p' > /sys/kernel/debug/dynamic_debug/control
Make sure debugfs is mounted before.
There is a scattergather fix in 4.8-rc1, but it has another regression, so
waiting for 4.8-rc3 and retrying with it could make sense.
Not sure if that fix is related, but should be fairly easy to try before
digging too
deep into this
-Mathias
