Dear Ben, > Based on your experience I might propose to change the automatic kernel > selection for i386 so that we use 'amd64' on a system with >16GB RAM and > a capable processor. Don't you mean change to amd64 for >4GB (or any RAM), never using PAE? PAE is broken for any amount of RAM. More precisely, PAE with any RAM fails the "sleep test": n=0; while [ $n -lt 33000 ]; do sleep 600 & ((n=n+1)); done and with >32GB fails the "write test": n=0; while [ $n -lt 99 ]; do dd bs=1M count=1024 if=/dev/zero of=x$n; ((n=n+1)); done Why do you think 16GB is significant?
