Hi,
I'm not sure if this is a reproducible issue and the system isn't one
on which I can experiment. The system is an amd64 system running
netbsd-8 from 20-June.
I created and brought up a tap0 interface, then a bridge0 interface
and accidentally entered the wrong interface for the bridge so it was
bridging tap0 and wm1 instead of tap0 and axe0.
When I ran ifconfig axe0 up, the system became mostly unresponsive -
it had a packet returned every ten seconds or so, then it paniced
about two minutes later:
tap0: Ethernet address f2:0b:a4:05:5a:73
panic: kernel diagnostic assertion "xfer->ux_state == XFER_ONQU"
failed: file "/usr/src/sys/dev/usb/usbdi.c", line 906

Any thoughts?
