--- Comment #5 from paul vixie <[email protected]> ---
similar LOR involving tcphash, 16-CURRENT as of this date (2025-12-28):

wlock order reversal:
 1st 0xfffff8000c4ed5e0 so_rcv (so_rcv, sleep mutex) @
/home/vixie/scratch/freebsd-src/sys/kern/uipc_socket.c:1429
 2nd 0xfffffe00c36cda10 tcphash (tcphash, sleep mutex) @
/home/vixie/scratch/freebsd-src/sys/netinet/tcp_usrreq.c:440
lock order so_rcv -> tcphash attempted at:
#0 0xffffffff80c0f23[Starting cron.]1 at witness_checkorder+0xbe1
#1 0xffffffff80b71011 at __mtx_lock_flags+0x91
#2 0xffffffff80dc555b at tcp6_usr_listen+0xfb
#3 0xffffffff80c4ec61 at solisten+0x41
#4 0xffffffff80c576ff at kern_listen+0x6f
#5 0xffffffff810f1a19 at amd64_syscall+0x169
#6 0xffffffff810c007b at fast_syscall_common+0xf8

it's happening at startup time, see the [Starting cron.] message which i placed
brackets around. restarting cron doesn't re-trigger. nor restarting sshd which
was started just prior.
