This is on a very recent -stable (like, as of just a couple of days
ago). Doing nothing in particular, ZERO_COPY_SOCKETS _not_ specified in
the config. This has happened twice this morning; if it happens again
I'll drop back to my older kernel, built back in May.
I've attached my config and dmesg; the stack trace is here:
