I did a cvsup & buildworld and the buildworld died pretty quickly on a mangled dir panic. The files that fsck relocated on the ensuing reboot were the ones updated by cvsup. I still need to boot SuSE to verify if this is a problem with FreeBSD or the memory configuration, but I was curious if anyone else had experienced this. It appears under -CURRENT and 5.4RC1 (tried reinstalling after the disk got mulched and it panicked trying to install perl). Machine spec: Tyan S2881 16GB PC2700 (former memory was 2GB PC3200) 2 WD disks attached to the onboard SiI3112 -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
