It would be >only courteous given that he's the author of this bug/feature. The feature is fairly important. Steve and one or two other people are the only ones seeing the problem after Kirk's fix was committed. Steve is the only person to report filesystem corruption caused by it. I'm not able to reproduce the panic, despite doing more than 20 "make world"s in an attempt to reproduce it. If we disable it by default then it will never get fixed because there will be no feedback from people who are still having problems with it. I WILL disable it prior to the 3.0.1 release if it isn't fixed by then, however. Meanwhile I'll look at adding something that will ensure that filesystem corruption isn't possible - I think this will amount to detecting the problem and panicing earlier. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
