woody upgrade to testing & unstable causes "illegal instruction"

[Derrell.Lipman@UnwiredUniverse.com]

Good evening.  I recently installed woody 3.0.0.  It was working fine, but I
wanted to install the latest version of quanta which required the latest
version of kde which required libraries only found in unstable.  I added lines
in sources.list to include debian testing and unstable, and the feeds that
provided quanta and kde.  Through dselect, I selected quanta, and then said
Install.

Many hundreds of package upgrades later, I have an up-to-date system that
works for many things, but gives "illegal instruction" on many apps.  (e.g. it
tried to upgrade ssh but sshd was giving an illegal instruction error; dig
also gives the error)

I tried running ldconfig (no parameters) to ensure that the the library links
were set up correctly following the massive upgrade.  No effect; still illegal
instruction errors.

I would sure appreciate any suggestions for getting things back to a working
state.  This is a non-critical machine so I was willing to play with unstable.
I guess I got what I deserve :-) but I know it can be fixed.

Thanks!
