The crash dump is 256MB :-) PLEASE gzip it gefore sending to me :-) > I figure Julian and/or > Kirk could use a gdb'able crash dump to track the softupdates panics > down better rather then have to depend on send-pr descriptions. me's da man.. basically what you do is one of two things: 1/ provide me with a crash-dump (gzipped) and kernel (-g) in ftp.whistle.com/incoming. also supply a readme saying who you are and what the files are and that they are for me (so someone else here doesn't delete them) you also need ot supply: the revision number of ffs_softdep.c and the approximate time/date of the checkout of the kernel sources. this is so we can check out a simlar aged tree to debug in.. or 2/ provide kirk and/or me with a login on a machoine where teh dump and debug kernel are in place in the compile directory. in other words put the dump in where the kernel was made and let us at it.. (all need to be readable by us of course). > > -Matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
