This CD should have a full non-symbol-stripped kernel, built with "options DDB" and "options BREAK_TO_DEBUGGER". From this, you will be able to tell us where it's failing. Because RC2 was not tagged, because We Fear CVS Tags(tm), you will need to use a date in order to create your own RC2. It is suggested that you build a standard version (useless for this type of debugging) first, to verify that you can repeat the error, so that you will be able to tell the difference between an error that went away because your source does not precisely match that of RC2, and an error that went away because there's a memory map issue that was effected by a larger memory disk image and/or a larger kernel image and/or the symbols being included, etc.. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
