I can try it again and post the error

What kind of troubles are we talking about? also I see that preemption
is now on by default. I have been running preemption on a 5.x box of a
long time now, no problems.

Yes I just found that out when I tried to load the Highpoint RAID
driver on FreeBSD 6, the system panics very early in the boot process.
This means that FreeBSD 6 is completely out of the question for this
system and I really did not want to run 6.x anyways, I'm migrating a
production 5.4 server to this new hardware.

What is SOS@? and where can I read the discussions about sata RAID
problems? I seem to have two options for this server:
(1) Get the ICH5R / Adaptec HostRAID working with 5.4 (as device ar0, ad4 + ad6)
(2) Find a (cheap) SATA RAID 1 card that is supported by the ar / ata
device in 5.4.

The problem with (2) is that I can't find any cheap (less then $60
USD) SATA RAID 1 cards that will work with device ar. I'm going to
post this problem to a new thread.

No I did not, how do I regenerate the database? normally I use pw or
vipw when I change that stuff and I've never been asked by mergemaster
to change those files.

Also with mergemaster it seemed like 50% of the 100 or so files that
where changed where just changes to the cvs doc revision /
timestamp... wouldn't it be better to install those files by default
instead of asking the user?

Not sure, I installed it on one of my home systems and I'm at work.

Thanks.
