Sure! I'll send you the trace.dat file off-list (it's almost 10 MB). > I definitely need to talk to the CSME guys, I can see that CSME is > alive even if you have AMT disabled. What is this CSME thing, anyway? And does this imply that the AMT is not really disabling itself (there's also a "permanently disable" option in BIOS that I have not dared pick..) > Problem: it's holiday season here.
