swtpm at /usr/bin/swtpm does not support TPM 2

is your system correctly usr-merged? (is /bin a symlink to /usr/bin)? was this system upgraded or freshly installed? anything else that is peculiar about it?
Code:
# ls -laF
total 64
drwxr-xr-x  19 root root  4096 Aug 13 09:32 ./
drwxr-xr-x  19 root root  4096 Aug 13 09:32 ../
lrwxrwxrwx   1 root root     7 May 12 15:25 bin -> usr/bin/

It's a fairly new install, I have a few Linux VMs and a Win7 Pro VM on it.
 
okay. could attach the output of strace -ff swtpm socket --print-capabilities as well as sha256sum /usr/bin/swtpm* /usr/lib/x86_64-linux-gnu/swtpm/*?
