Having weird DNS issues since update to firmware 6.4.2.6-4.1.1.9_51442

We have 81 Aruba 225 IAP's in a cluster. We have a VLAN setup for our wireless traffic and our wired traffic runs on a different VLAN. Before I updated our firmware to version  6.4.2.6-4.1.1.9_51442, everything worked fine, but now I am unable to resolve DNS in our reverse lookup zone, forward lookup works fine. Here is the kicker... if I cable the PC in, everything works fine. Our VLANS are routed on a layer 3 switch, no filtering or anything, it just routes all traffic between VLAN's. Everything else works fine: Internet, Forward DNS lookup, ping, etc... any ideas???
