"The Cisco StackWise technology requires that all units in the stack run
the same release of Cisco IOS Software. When the stack is first built, it
is recommended that all of the stack members have the same software feature
set - either all IP Base or all IP Services. This is because later upgrades
of Cisco IOS Software mandate that all the switches to be upgraded to the
same version as the master."

So it looks like you'll need to downgrade the ipservices box or upgrade the
ipbase boxes.
