Interesting, have you tried 4.2 kernel from R3.1 unstable repository?
Do you have any means of collecting kernel/xen messages? I guess you've
already disabled "quiet" kernel option and also removed "console=none"
from xen cmdline.
If this doesn't help, try adding "noreboot" and "sync_console" to
xen cmdline.
If you have serial console (on docking station?) if would be easier to
reliably get log messages.

I just tried the 4.2 kernel on the stick created by AEM under
R3.2rc1; It seems to work as well as 4.1.
I'll try 4.4 again removing those boot options.
Unfortunately, the only docking station here is the kind lacking
serial ports.

A bit more info:
Removing rd.antievilmaid from 4.4.12 options doesn't help; it still
restarts. I also tried 4.4.14 in the unstable repo but that did not help.
It appears to be an incompatibility between kernel version 4.4 and tboot.

I am able to get 4.4.* to boot now! The trick was to add
'min_ram=0x2000000' to the tboot options like I used to do--the AEM
README describes how.
But now I cannot get AEM to seal the secret. Nothing at all about AEM is
displayed during startup, even though rd.antievilmaid is on the kernel
options line.
