Still a problem with 4.11.0-rc2-ARCH+
xhci tracing can be added with:
mount -t debugfs none /sys/kernel/debug
echo xhci-hcd >> /sys/kernel/debug/tracing/set_event
Here's the log I was able to obtain today, dmesg + ftrace at the time
of the crash:
https://bugzilla.kernel.org/attachment.cgi?id=255419
USB keyboard and mouse was plugged when I reproduced this.
Please let me know if you need more info.
Thanks, I'm looking at the logs and so far the most suspicious looking entry is:
[ 257.060941] rtsx_usb-254 0.... 119946155us : xhci_urb_enqueue: ep1out-bulk: urb ffff880105a93300 pipe 3221259520 length 0/12 sgs 0/0 stream 0 flags 00010000
[ 257.063601] rtsx_usb-254 0.... 119946162us : xhci_urb_enqueue: ep0out-control: urb ffff880105a93300 pipe 2147484928 length 0/0 sgs 0/0 stream 0 flags 00100000
It enqueues the same URB, without ever giving it back or actually queuing any trbs for
the urb, wel,l it might just fail to enqueue it in the first place.
I need to search for a URB that has been dequeued but never given back in the trace
