In most cases you will be better off disabling spanning tree.  When an 
interface goes down with spanning tree enabled (and configured for slow 
start) it may be a minute or two until traffic will pass.  During the 
boot process of the kernel it is not uncommon for the interface to be 
reset and cause a short outage in the middle of the boot process.

Ciscos also take time to auto-negotiate, you might need to lock the 
interface to a data rate for the same reason.
