If you do an i386 (userland) installation then you must either select
expert mode to get a choice of kernel packages, or else install the
'amd64' kernel package afterward.

In what way?

Debian users are now generally installing a full amd64 (userland and
kernel installation.  The default installation image linked from
www.debian.org is the 32/64-bit net-installer which will install amd64
if the system is capable of it.

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.

Ben.
