That's odd, certainly not the corruption I first suspected.

I think this will be fixed by:

commit 08d73f1a4499cfe7c3121ff2ecdd36729c5f3544

    sna: Only couple up a proxy->rq when inserting into the request->buffers list

    Otherwise, we may never decouple it again afterwards leading to a
    dangling pointer dereference.
