Description Zdenek Kabelac 2016-12-10 11:25:38 UTC 
Description of problem:

Seem   4.9-rcX  kernels have troubles to use tpm.

I've already reported on lkml - but no interest so far:

http://www.gossamer-threads.com/lists/engine?do=post_view_printable;post=2550382;list=linux

And my T61 is not able to suspend - assuming it's related.
Also boot is very slow (timeouting udevd)

Unsure - possible related to  extra debug settings for rawhide kernels?

Comment 2 T.Paul Lee 2017-01-10 01:02:01 UTC 
I ran into the same problem with v4.9.0 also on Thinkpad X61 and gcc 5.4.0.
On boot up, the system panicked at this
tpm_tcg_write_bytes+0x30/0x50 location.

I was hoping to exclude the TPM module, but had no clue how to do that.
But I am able to bypass and move on by disabling (BIOS) the TPM (so-called security chip I think).  Hope that someone can address this problem.
Comment 3 Laura Abbott 2018-04-06 18:22:07 UTC 
Doing some pruning, this bug looks to be several kernel versions old. Please test on a newer kernel and reopen if the problem still exists.
