incompatibility issue - WLC 5508 and ACS 5.4

Hi,

This is my scenario:

Cisco WLC 5508 firmware 7.4.110.20 and ACS 5.4, two WLAN eap/tls, many client  can't connect to WLAN and on ACS i receive the following error:

Authentication failed : 11051 RADIUS packet contains invalid state attribute

workaround:

1 -Check the network device or AAA Client for hardware problems.

2-known RADIUS compatibility issues.

3-Check the network that connects the device to ACS for hardware problems

there are some incompatibility issue between WLC and ACS ? the compatibility matrix document for wireless imposes the 7.5 firmware for WLC.

What do you think is possibile ?

Are there any other errors shown in the details of the failed authentication?

We may need to look at service logs in debug mode, opening a TAC case would be the best way to go about this.
