Have you edited the rss php files?
/wp-includes/feed-rss.php
/wp-includes/feed-rss2.php
This might have more to do with rewrite rules than with the permalink structure.

What does your htaccess look like?
Thank you for answering and I will definitely read that.
I did edit the files, then replaced them with copies of the originals when nothing was resolved.
htaccess
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} ^/(stats|failed_auth\.html).*$ [NC]
RewriteRule . - [L]
</IfModule>
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Still, no resolution. To date, I have disabled every plugin – one at a time and replaced all the rss files. I am still confused.
Forgot, I also reverted to the default theme.
Oddly, the more I read up on this (a few people have voiced my theory) and on looking at the my own sites last working feed. It coordinates with my last update and the permalinks structure of categories.
Any other theories?
