I agree that currently a 32bit operating system is
better for production use on AMD Opteron CPUs.
When I first learnt that Geoffrin uses 64bit Linux I
was very surprised. I really don't understand why
Geoffrin was set up to work in 64bit mode, since it is
a production machine and stability is a critical
issue, so we should use 32bit Linux (or freebsd).
I don't mean that AMD Opteron is not good hardware. I
just say that it is too early to install 64bit
software, because probably it is more buggy than the
32bit versions.

In just three weeks we've had two hard

two instances of file
corruption.
We are using a 64-bit Kernel on Geoffrin, right? I
wonder if this is a
good idea, since the Kernel hackers working on the
AMD64 Linux port have
just fixed several nasty bugs that could lead to
data corruption and
crashes. According to Andi Kleen, one of the lead
hackers working on
x86_64-Linux, AMD64 isn't really ready for
production use and has still
lots of hack value.
Maybe it might be a good idea to stick with a 32-bit
system on Geoffrin
until the Linux codebase for AMD64 stabilizes a bit
more?
