Hello,
Has anyone else noticed a similar odd behavior with AMD64 and 9.0
prerelease (as well as RCs and betas)?
On my 12 core (2*4162EE) the whole system just freezes quite often
without any warning, without any messages being logged. Neither is
there any panic message from the kernel. The system just suddenly
hangs such that there is no alternative but to reboot using the
reset button.
At the moment I don't have any further info about the cause of the
problem, but quite often the freeze has happened when there has been
some network activity.
Does anyone have an idea how to start tracking down such a problem?
I mean anything in addition to this...

I experienced this a rather long time ago with an AMD X2600 (Barton?)
processor. The machine would freeze when I did some rapid
mousing/clicking in and out of a window. Nothing in the logs. If I
stayed out of X things were just fine but this was my home machine and
why should I have to stay out of X? I figured FBSD dev was just running
behind the Intel dev and time would fix it. Or Xorg dev would even up.
In any case it went away in the next release. It was never *that* much
of a problem; consistent but not often. Your freezing appears to be more
frequent than was mine. At this point in the release cycle I think the
only issues they find are for weird corner cases. Perhaps you have one.
Or it's hardware :( Try a different NIC for a while.
