I have now installed the AMD64 version on the server. It has been running stable now for some hours with alot of load and all the 6 GB activated.

I'm a bit worried that one works for you while the other doesn't; I extensively tested the code on both platforms with 8GB of RAM. Scott Maybe I missed something in this thread, but what does it have to do with the amr driver? The first thing that came to mind was something with PAE and how it affects PDE modifications. On i386, it might be worth trying these combinations: 1. SMP, NO PAE. 2. UP, PAE. 3. UP, NO PAE. As we already know that "SMP, PAE" for you has problems. Bounce buffers were horribly broken in 5.3-RELEASE for amd64 and i386, and the amr driver itself was unreliable in using them even when they worked (the amr driver cannot do 64-bit S/G right now). I fixed all of this stuff a few weeks ago. I tested all of this extensively under PAE, but you're correct that this particular problem could very well be related to pmap problems specific to i386.

I have updated my source again with cvsup (RELENG_5), compiled the source and installed the new world and kernel, but the server is still unstable with >= 4GB.
