Hi Boris,
Excellent idea. With CONFIG_DEBUG_OBJECTS_FREE=y I've hit this twice:
ODEBUG: free active (active state 0) object type: timer_list hint:
xhci_stop_endpoint_command_watchdog+0x0/0x2b0
So I'll try to hunt that down on the xHCI side and report over to
linux-usb. Sorry for the unrelated noise on this patch -- my guess is
that timing changed just enough for the xHCI driver to hit this. :)
