Greg's debugging this on the machine here at the moment, which is crashing the same way in what appears to be the same place. If anyone else wants to take a crack it, the magic vinum debug number needed is 328 and not 324. So far Greg's discovered that the field is correctly set a little while before the crash, and then becomes NULL for no apparent reason. Looks like a really nasty bug. The nice thing is this loaner machine has no real job to do besides crashing, so it can crash as often as required. :) -- Parag To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
