Public bug reported:
I just installed Intrepid on my Core 2 Quad system.
Core 2 has AMD64 support (or EM64T as Intel calls it).
As a developer of software, I'm interested in being able to build my
programs in 64bit to check for portability. For this reason, I tried
out the 64bit Intrepid. There were a lot of issues and headaches with
that, so I decided to go back to 32bit.
I still wanted to be able to build and run 64bit binaries though, so I
had the idea of installing the appropriate libc/gcc packages for amd64
(which exist) and then installing the appropriate kernel image (which
does not exist).
I was able to download linux-
image-2.6.27-8-generic_2.6.27-8.17_amd64.deb from the mirror and install
it using dpkg --force-architecture. I booted, and everything is
copacetic. Even the initramfs was generated properly (with what I
assume is a mix of 32bit userspace utilities and 64bit kernel modules).
I don't have any hardware that requires restricted modules, so I didn't
need to worry about that — if I did, perhaps things wouldn't be so happy
right now.
I've heard that there are some specific issues with running a system
like this (for example, that the usbfs interface doesn't have the
correct 64/32bit thunks in place) but I've yet to encounter a single
issue. Certainly it's working well enough to be useful.
It's worth it to provide an official package for this, I think.
