I have been trying to understand the failure better:
(kgdb) frame 10
#10 0xffffffff80473265 in usb_transfer_complete (xfer=3D0xffffff00045cbc00)
at /red/public/freebsd/sources/stable/sys/dev/usb/usbdi.c:949
949 STAILQ_REMOVE_HEAD(&pipe->queue, next);
(kgdb) list
944 #ifdef DIAGNOSTIC
945 xfer->busy_free =3D XFER_BUSY;
946 #endif
947 KASSERT(STAILQ_FIRST(&pipe->queue) =3D=3D xfer,
948 ("usb_transfer_complete: bad dequeue"));
949 STAILQ_REMOVE_HEAD(&pipe->queue, next);
950 }
951 DPRINTFN(5,("usb_transfer_complete: repeat=3D%d new head=3D=
%p\n",
952 repeat, STAILQ_FIRST(&pipe->queue)));
=46or reference:
#define STAILQ_NEXT(elm, field) ((elm)->field.stqe_next)
#define STAILQ_FIRST(head) ((head)->stqh_first)
#define STAILQ_REMOVE_HEAD(head, field) do { \
if ((STAILQ_FIRST((head)) =3D \
STAILQ_NEXT(STAILQ_FIRST((head)), field)) =3D=3D NULL) =
\
(head)->stqh_last =3D &STAILQ_FIRST((head)); \
} while (0)
Looking at the data:
(kgdb) p *pipe
$15 =3D {iface =3D 0x0, device =3D 0xffffff009c1e4a00, endpoint =3D=20
0xffffff009c1e4a38, refcnt =3D 1, running =3D 0 '\0', aborting =3D 0 '\0',

repeat =3D 0 '\0', interval =3D -1, methods =3D 0xffffffff80a6e340}
(kgdb) p pipe->queue
$16 =3D {stqh_first =3D 0x0, stqh_last =3D 0xffffff000c8576a0}
(kgdb) p pipe->queue->stqh_first
$17 =3D (struct usbd_xfer *) 0x0
And, of course,
(kgdb) p pipe->queue->stqh_first.next
Cannot access memory at address 0x290
If the kernel had been built with INVARIANTS, presumably the prior assertio=
n=20
would have been triggered. It is not clear to me how the transfer ended up=
=20
in this bad state. Could the "USBD_NOMEM" status be a clue?
(kgdb) p *xfer
$6 =3D {pipe =3D 0xffffff000c857680, priv =3D 0x0, buffer =3D 0xfffffffef5b=
69ff0,=20

RequestType=20

wValue =3D "\001\003", wIndex =3D "\t\004", wLength =3D "\022"}, frleng=
ths =3D=20
0x0, nframes =3D 0, device =3D 0xffffff009c1e4a00, dmamap =3D {
segs =3D {{ds_addr =3D 23408640, ds_len =3D 16}, {ds_addr =3D 23355392,=
ds_len =3D=20
2}, {ds_addr =3D 0, ds_len =3D 0} <repeats 31 times>},
nsegs =3D 2, map =3D 0xffffff000cbf5e00}, allocbuf =3D 0x0, rqflags =3D=
1, next =3D=20
{stqe_next =3D 0x0}, hcpriv =3D 0x0, timeout_handle =3D {
c_links =3D {sle =3D {sle_next =3D 0x0}, tqe =3D {tqe_next =3D 0x0, tqe=

0x0}}, c_time =3D 0, c_arg =3D 0x0, c_func =3D 0,
c_mtx =3D 0xffffffff80b12600, c_flags =3D 0}}
I am getting out of my depth. I will spend some more time trying to learn=
=20
this code but would appreciate pointers.
Cheers,
