Phone resets when computer sleeps

We are seeing a problem with various model Cisco phones resetting when the computer attached goes to sleep and wakes. We are running ISE with EAP for the computers. We see the same problem when the phone is using MAB or 802.1x. Has anyone else seen a similar issue? The only thing that we can see is a reported carrier lost in the radius transaction for the phone when the computer sleeps/wakes.

Switches are 3850's. Phone

Switches are 3850's. Phone models we have seen the problem with are the 9971's (load 9-4-1-9) and 6941's (9.4.1.3). Port configuration is consistent across all switches (3.3.1SE). Each access closet has it's own specific voice and data vlan.
