Do you know where this is? I tried compiling from source, but still get
the error. I assume it's because I'm still compiling using 32-bit

I was trying to install various kernel images, including one I compiled
myself using make-kpkg. I would get past the kernel installation to the
initrd installation and then see this:

Unpacking kernel-image-2.6-amd64-generic (from
.../kernel-image-2.6-amd64-generic_100_i386.deb) ...
Setting up kernel-image-2.6.8-9-amd64-generic (2.6.8-8) ...
cpio: (0x00000000): No such file or directory
cp: cannot stat `(0x00000000)': No such file or directory
run-parts: /usr/share/initrd-tools/scripts/e2fsprogs exited with return
code 1
Failed to create initrd image.

I'm ok with alsa not working. Are there any other glitches that might
affect using this on a production server?

I guess what I really want to know is: what is the best way to get the
64-bit performance advantages out of my hardware? I don't want glitches
with the software I'm running, such as Apache2, mod-perl, mysql,
postgres, and postfix. I would be OK with my currrent setup (32-bit
userland, 64-bit kernel), but it seems like there are reliability issues
doing this. Are these all taken care of by moving to 64-bit userland?
Are there any arguments *against* moving to 64-bit userland?

Thanks for your answers so far
