Hello all,
i'm working on usb_autosuspend for ath9k_htc and triggered this
oops. Currently i do not know if real bug is in ath9k_htc or in
xhci. Same adapter with same kernel and my patches work fine on ehci
host... so may be it is xhci.
Which kernel version is this oops on? I suspect it's an xHCI issue.
Please turn on CONFIG_USB_XHCI_HCD_DEBUGGING and CONFIG_USB_DEBUG and
send me dmesg, from the beginning of connecting the device to when it is
suspended and then resumed. That will be a lot of output, so feel free
to compress it.

Hi Sarah,
i use 3.10.0-rc4-wl-00055-gc341e6d, and i also tested v3.8 and v3.9 with
same results.
Suddenly i'm not able to get log after crash. This chip do not support
serial port and ehci debug port is not available i any way - i tried it
really hard with soldering iron :) There is even no ethernet connection
- only usb adapter. If you have some ideas, please tell me.
