What model is your computer and what version of Linux are you using?

I have verified that the tpm_tis driver has been properly loaded and the pcrs file contains non-0 values.

 

When running trousers in the foreground with debug options enabled I receive the following output:

 

TCSD TDDL ioctl: (25) Inappropriate ioctl for device

TCSD TDDL Falling back to Read/Write device support.

TCSD trousers 0.3.1: TCSD up and running

 

Thanks,
