--- Comment #8 from John Baldwin <jhb@FreeBSD.org> ---
Humm, the only fix I can see that would be relevant for GELI in particular =
(and
might have resulted in a hang if the hardware was waiting for more data due=
 to
an S/G list being too small) is this commit:

commit 70efe1a2fe13642732e56c7f040fe63f62bc6a6b
Author: John Baldwin <jhb@FreeBSD.org>
Date:   Mon Feb 6 13:51:57 2023 -0800

    ccr,ccp: Fix argument order to sglist_append_vmpages.

    The offset comes before the byte count.

It would have worked fine with cryptocheck or other use cases, just not GELI
when using unmapped disk I/O (which I think is the only crypto consumer that
uses the VMPAGES buffer type).  That commit has been merged to stable/13 and
will be in 13.3.  It was not included in 13.2.  I'm going to optimistically
close this bug, but if anyone reports issues on 13.3 or newer we can reopen=
 it.
