Hello,
with a quite recent SMP -Current machine, I've seen a message reporting a LOR
(the sources have been cvsup'ed around 07h00 GMT yesterday).
in /var/log/messages :
May 25 18:09:38 machine kernel: lock order reversal

FreeBSD machine 5.1-BETA FreeBSD 5.1-BETA #21: Sat May 24 16:28:28 CEST 2003
rot@machine:/files3/obj/files3/src/sys/SMP i386
The machine is a BP6, with no ACPI (the BIOS seems to be broken in this
regard) and the straight SMP kernel config file.
Happy hacking
