I don't understand master was rebooted so check runtime configuration of 
sysctl net.inet.carp.preempt on master.
Check also /var/log/messages on both computers, sysctl 
net.inet.carp.demotion on master (CARP may be demoted due to 
interface/pfsync errors. CARP with preemption may be demoted also by 
down any other interface with CARP on the system).
Check firewall on slave, may be it block ingress packets from master.
