There might have been driver problems in 5.2.1 which cause the data corruption. Sure, but it'll have to wait until this weekend. I'll repost when I get it installed, etc. If not by this weekend, then it'll have to wait until next weekend. Ok, after more experimentation, here are some results: With no RAID1 5.2.1 and 5.3b7 both produce consistent md5 sums of the file (that is, with a small installation on one of the hard drives). With RAID1 setup using atacontrol following the instructions on http://www.techno-obscura.com/~delgado/notes/fbsd-ich5SATAraid.html both 5.2.1 and 5.3b7 produce inconsistent md5 sums of the file on consecutive runs. Further, it may be related to the size of the file, as in 5.3b7 (I haven't tried this with 5.2.1 yet) performing md5 sums of the dot-files in my home directory produced consistent results. I'll be installing the server using only one hard drive, with the second as one big partition used to hold backups, but I'd like to be able to install with all partitions on a RAID1 setup. So, any suggestions on where to go from here?

md5 giving inconsistent results
I just installed 5.2.1-RELEASE on a RAID1 setup (atacontrol using Sil0680 chipset), and was in the process of transfering files from my old server. However, I'm having an issue with the md5 sum of a file. Here's my uname -a: FreeBSD tigger.weller-fahy.com 5.2.1-RELEASE-p11 FreeBSD 5.2.1-RELEASE-p11 #0: Thu Oct 14 00:17:32 CEST 2004 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/GENERIC i386 Here's the program I'm using: which md5 /sbin/md5 Here's the directory listing of the file (sized match on old server, windows box, and new server): ls -al total 714570 drwxr-xr-x 4 dave dave512 Oct 13 20:45 ./ drwxr-xr-x 16 dave dave 1024 Oct 13 21:14 ../ -rw-r--r-- 1 dave dave 731327140 Oct 11 21:52 files.tar.gz -rw-r--r-- 1 dave dave162 Oct 13 20:44 files.tar.gz.md5 drwxr-xr-x 2 dave dave512 Oct 11 22:21 php/ drwxr-xr-x 3 dave dave 1536 Oct 11 21:39 qmail/ Here's the md5 from the old server: dave[tigger]/files md5 files.tar.gz MD5 (files.tar.gz) = 986a79245120f645b2a546fa6567d8ab Here's three runs of md5 from the new server: md5 files.tar.gz MD5 (files.tar.gz) = c57f4d82f32d698c16f0d792761ce9d6 md5 files.tar.gz MD5 (files.tar.gz) = 933608fc706c652b7d3ef2f5115d3ead md5 files.tar.gz MD5 (files.tar.gz) = d8cd06f700b612fee72c39d5bc39df5a And the md5 on a windows box: C:\Documents and Settings\dave\Desktopmd5sum files.tar.gz 986a79245120f645b2a546fa6567d8ab *files.tar.gz Just tried the same thing using md5deep from ports on the old and new server, and got similar results: md5 sums are inconsistent when calculated on the new server. So. What's my next step in figuring this out? I was using the following flags for optimization, but stopped and rebuilt world with no optimization flags (except MAKE_IDEA=yes and LEAPSECONDS=YES). CPUTYPE?=athlon-xp CFLAGS= -O -pipe CXXFLAGS+= -fmemoize-lookups -fsave-memoized MAKE_SHELL?=sh COPTFLAGS= -O -pipe MAKE_IDEA=YES # IDEA (128 bit symmetric encryption) LEAPSECONDS=YES I'm at a bit of a loss, and am about ready to try a reinstall, any suggestions other than that and memtest86 (which I'll be trying next)? Oh, and any pointers towards information that I failed to provide will be gratefully accepted.
