I added VLAN 80 on the controller, although it shouldn't have any impact on this issue. All VLANs are up:
Vlan Status

83 10.0.83.7/255.255.255.0 Enabled Up 1 Disabled Regular GE1/0 N/A
196 10.0.199.34/255.255.252.0 Enabled Up 1 Disabled Regular GE1/0 N/A
The Cisco switch has no IP addresses and I can't add any, but I can ping the PA addresses from the controller:
(RCH_AMC4) #ping 10.0.82.1
Press 'q' to abort.
Sending 5, 92-byte ICMP Echos to 10.0.82.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0.746/2.7964/10.07 ms

I can also ping them from the Cisco switch. I'm thinking it's an issue on the PA - found this post on a similar issue when connected to an ASA firewall:
