What's on Gig0/1, Gig0/17, Gig0/18, Gig0/19, Gig0/23, Gig0/24? What
port is the PF box on?

Unless topology suggests otherwise, 'spanning-tree vlan 8 root' to
force this to be the root bridge. Also, enable portfast on Gig0/21 and
Gig0/22; Gig0/15 and Gig0/20 (assuming there really is just a phone
and desktop behind them) need 'spanning-tree portfast trunk'.
