I'm seeing the same problem with linux-image-4.9.0-7-amd64:4.9.110-1 from the 9.5 point release running on Xen/pvgrub.
In case it's useful, here's the verbose kernel log: [ 2.028120] registered taskstats version 1 [ 2.028149] zswap: loaded using pool lzo/zbud [ 2.030226] ima: No TPM chip found, activating TPM-bypass!
