Basically, what this means is that a situation was detected, that may lead to the possibility of a deadlock. Some of these are real bugs that need fixing, others have been verified to be false alarms. You can compare the ones you have seen with the list maintained at http://sources.zabbadoz.net/freebsd/lor.html and see if you are seeing a LOR that has already been reported (more than likely). Please also note that several LORs have probably been fixed without this page being updated, so don't worry too much about the fact there are a lot of them on that page in the "unknown" state. In short, unless you yourself are doing development work in the kernel and see these relating to your own code, you probably don't need to worry about it. Gavin
