It is about the following LOR: http://sources.zabbadoz.net/freebsd/lor/261.html lock order reversal: 1st 0xc2e03e00 bufwait (bufwait) _at_ sys/kern/vfs_bio.c:2443 2nd 0xc3592200 dirhash (dirhash) _at_ sys/ufs/ufs/ufs_dirhash.c:254 Quoted from the thread about this topic from last januari: ============ Gavin_at_ writes: Cool. It's always good to have more people using and testing -CURRENT, I just wanted to make sure you knew what you were getting yourself in for :) > I pulled out the 'extra debugging', made world and kernel, and rebooted. > Notice the 5th line of da7's drive ID being interleaved with 'SMP: AP CPU #1 Launched!' > > I'm fairly sure this is not a good thing, if for no other reason that 'apparent garbage' in dmesg is not useful. It's not a good thing, but it's a known issue and is purely cosmetic. ============= Only in my case it seems not so harmless. I get this one on rebooting, which then freezes the process. Under 7.2 the system (although from 2002) did reboot. Could this LOR be responsible for not rebooting? If not, how do I go about in finding what does prevent the reboot. It just halts at the stage where it gives the uptime after syncing all disks. Normaly reboot follows, but there are no messages for that. And a hardware reset is required. --WjW cpu I586_CPU cpu I686_CPU ident ASTERBSD # To statically compile in device wiring instead of /boot/device.hints #hints "GENERIC.hints" # Default places to look for devices. # Use the following to compile in values accessible to the kernel # through getenv() (or kenv(1) in userland).
