Hi,

Whever we use tboot 1.9.4 on platforms such as RHEL 7.3 beta, or CentOS 
7.2, with Intel TXT enabled in the BIOS, it reboots constantly and the 
last thing we see before the reboot is:


TBOOT: setting MTRRs for acmod: base=0x7bf00000, size=0x20000, num_pages=32
TBOOT: The maximum allowed MTRR range size=256 Pages
TBOOT: executing GETSEC[SENTER]...

In centOS 7.2, if I disable Intel TXT in the BIOS then at least the OS is able 
to boot to completion.


Is this a known issue?
