Good Evening, Checked nightly logs to discover that there had been two lock order = reversals last night on my SMP 5.2C machine. They are listed as: lock order reversal 1st 0xc7975dec vm object (vm object) @ /usr/src/sys/vm/swap_pager.c:1314 2nd 0xc0788d80 swap_pager swhash (swap_pager swhash) @ /usr/src/sys/vm/swap_pager.c:1823 3rd 0xc1042738 vm object (vm object) @ /usr/src/sys/vm/uma_core.c:873 Stack backtrace: lock order reversal 1st 0xca738038 filedesc structure (filedesc structure) @ /usr/src/sys/kern/sys_generic.c:901 2nd 0xc0752d80 Giant (Giant) @ /usr/src/sys/fs/specfs/spec_vnops.c:377 Stack backtrace: The backtrace for the second LOR was thankfully still on screen, I've = taken a screen shot and it can be located at: http://parallax.alastria.net/~peter/xenon-lor1.jpg I'm going to cvsup to current shortly, I'm interested in trying the new schedular. If anyone from core needs access to the machine to poke, let = me know. Kind regards, Peter. Machine dmesg is as follows: Copyright (c) 1992-2004 The FreeBSD Project.
