We have two problems with Intel AMT and FreeBSD.
First:
On AMT version: 8.1.20-build 1336 AMT stop responding about five minutes after booting FreeBSD, it's FreeBSD 9.1-STABLE, 64 bit.
On Linux AMT works fine. We suspect driver, but it's similar like on Linux.
Second:
We have shell scripts to manage computers, on version 5 (older computers) we can sending command like:
curl -m 3 --anyauth -u user:password -d amt_html_rc_radio_group=2 -d amt_html_rc_boot_special=13 http://ip:16992/remoteForm
to power on and normal boot.
But on version 8 scripts stop working, forms are the same. Is there any changes?
Can you show us the way to resolve problems?
