My guess is your TPM is disabled and/or deactivated and it that mode doesn't like the sequence of commands we are sending to it. Well, I guess the best is to revert the patch for now. I'll send a patch for this.
What does
find /sys/devices -name active | xargs cat
currently show? If it shows a '0', can you try one other thing? Go into your machine's BIOS and find the TPM menu and enable/activate the device and try again the 'find's and suspend/resume again?
Thanks.
Stefan
