Well, a 2.8 CD wouldn't have worked but you now burned a more recent CD and you are getting the panic again? The question is what is the console output above the 'lockmgr' line ? i.e. all I see there is part of the backtrace, and not the actual reason for the panic. It's quite possible that it is a software bug that is exploding it.
Antonio had a similar issue with the hammer stage 2 mount where it couldn't run the REDOs (which is stage 2) and then refused to mount because of that. It didn't crash but it did refuse to mount, and I think Antonio is working on a boot-time setting to tell hammer to ignore a stage 2 failure and continue on with the mount anyway. However, your crash is slightly different... it's an actual crash, which means that there's a software bug somewhere. The hammer volume might still not be able to mount without the variable Antonio's has been working on, but we should be able to track down and fix the panic. -Matt Matthew Dillon <dil...@backplane.com>
