I'm not sure what to tell you. Did you look into the GTK installation failure? For WPA-PSK, there's 1 4-way handshake and the STA installs 1 PTK and 1 GTK. For WPA2-PSK for IBSS, there are 2 4-way handshakes and the STA installs 1 PTK and 2 GTKs. If the peer's GTK isn't installed, the STA won't be able to decrypt the peer's broadcast frames. Do you have a sniff of the failure? What's failing? Does it work if you use static IP addresses and static ARP entries?
