Hi,
Since we are discussing AMD64 with 8GB RAM, I also would like to point my
problem.
I'm still looking for possibility to run FreeBSD 5.3-STABLE with more
than 4GB RAM
on Dual amd64 2.2GHz machine (IBM @server 325) with ServeRAID 6M (ips
driver)).
Right now I'm using only 4GB RAM and this server is in production.
#uname -an

As Scott said a few months ago, problem is below:
"The ips driver looks like it will fail under heavy load when more
than 4GB
of RAM is present. It tries to force busdma to not defer requests
when the
bounce page reserve is low, but that looks to be broken and
will result in corrupted commands."
Are the ips driver and bus_dma problems fixed yet in STABLE tree?
Is it worth to try source update and see how it works? I'm afraid to do
so, since it is production server.
Yes, I (hopefully) fixed the problems that I pointed out, and I also
locked it and added crashdump support. It is reported to be stable and
fast now, so you won't go wrong by updating. These changes are in both
5-stable and 6-current.
Scott
