I know that Christian has been looking into this. My initial reading based on a quick skim was that the life cycle of early vnodes in file system mount had changed as a result of the VFS locking work, but Christian has indicated to me that the bug isn't reproduceable 100% of boots for him, and that Jeff felt this might reflect a race. Does this panic occur for you every boot? If you set debug.mpsavevfs=0 in loader.conf, does that make any difference? I may have the opportunity to work on this this weekend, but not entirely clear. If Christian is already running with it, I'd much rather let him take this one on as I have a lot of other things on my plate. Robert N M WatsonReceived on Thu Sep 29 2005 - 19:13:26 UTC
