I saw that too and modified something to get the driver to load. Dang, I should have written down what I was doing at the time.

I can take the ownership of iTPM, but don't run testsuite.

I have take a look the tpm_tis code a bit more.
"default time out" values should be set before call request_locality()
in tpm_tis_init function.
This is the reason why first modprobe with force=1 is fail.
