The line I suspect that is causing you trouble is:
spanning-tree bpduguard enable
That's probably the culprit because your Linksys switch is running the Spanning Tree Protocol which runs on all interface. The Cisco switch receives it, and because of the "spanning-tree bpduguard enable" it then disables it.
Oh, and I wouldn't run a "macro description cisco-desktop" on a switch<>switch connection..
